Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

I would start looking on pinterest or google images, take note of the rooms that you think look nice. Then try and find affordable ways to make your space look similar. If you like having minimal stuff, that's cool but I think when you start filling out your home a little more it will feel more inviting. Just start will small stuff and figure it out as you go.

this. this is all true
i bought on old house. the previous owners had big dogs living with them. eveyfucking thing is broken and scratched to fuck, from the dogs.
windows broken
window screens torn to shreds
window blinds, all wrecked
window trim, mauled to shit
wood floors scratched and mauled to shit
walls, wall trim scratched and torn to shit
door knobs on screen doors broken, torn off
big holes dug everywhere in back yard

dogs, especially big dogs, absolutley destroy a house. the belong outside as a a farm animal, work dog, guard dog, whatever. they dotn fucking belong inside the house.

Me and my bro built a prototype pier extention that theoretically would have eliminated the need to sink pylons by...
>bolting the pylons to a crude box aboard a pontoon boat
>Pushing the assembly overboard from the boat
>Dumping bags of concrete into the submerged box and allowing it to slowly sink into the mud
I-it... didn't work out... But we did have fun laughing at badly we failed.

>What's stopping a guy from ripping apart an old refrigerator and making an air conditioner from it?

Nothing, but you will be disappointed by the performance achieved in exchange for your efforts.
Your average reefer is only around 300~500 BTU's, and as others pointed out, a 10Kbtu unit is not that expensive.
>>
A good vacuum pump will run you about as much as an excellent condition second-hand AC, and a few bucks more will let you buy a brand new one.

AC compressors are very cheap online. The most expensive components are the controls and the know-how to make it work efficiently without either burning itself or frosting up all the time.

You'll have to figure out a way of putting everything in a functional and good looking enclosure. You would be much better off to find an old AC, swap the worn compressor and refill it with refrigerant than hacking stuff together like a poorfag.
>>

>OP is mega retarded and a mega faggot and mega broke that he thinks using a refrigerator to cool a room is better than using a proper ac unit, and i hate him.

i got a window unit for about $150
installed it in window in the living room of a single story 1000 sq ft house. it made the living room and attached kitchen, cool and comfy. and even the two bedrooms and bathroom down the hall became comfortably tolerable

Get into better plastics, especially ABS. ABS is strong and temperature resistant enough for automotive use, and it’s cheap as. Polycarbonate is the other one I’d look at. Nylon less so, but its flexibility combined with its strength may be handy. TPU and similar stretchy filaments would also be very useful to be able to print, especially with a dual filament printing setup. Knowing how to choose the right plastic for the job is half the battle.

If you’re designing custom parts, then try to design parametric models that can be easily customised to suit a variety of customer requirements. For enclosures and brackets and such. Could do this with proper CAD tools or something like OpenSCAD.

Also get yourself a good selection of heat-set inserts and other things to add into your prints.

That Slant 3D printing channel has some good tips for professional design.
>>
>>2795331
I watch a lot of slant 3d and a few other printing channels. Havent really messed with any of the other plastics besides TPU and a bit of ABS. I am aware of some of their properties though. Interested in Nylon, Glass filled Nylon, and probably filament with glass beads or other exotic materials.

The design is where I feel im limited most. I have been able to design some organic shapes on tinkercad, but nothing advanced like being able to sculpt something like a computer mouse. I know I have to find a modeling solution besides tinkercad. Have been pushing it to near its limits. Hate feeling like im going to be starting from zero. Also im wondering if I can fill in some gaps with 3d scanning and AI in the not so distant future.

The heat set inserts is a pretty good idea. I have designed with dovetails in the past, but heat set inserts can really make a prototype look professional.

I don't want to be too entirely tied down to 3d printing either though. I have a small diode laser I have cut some parts on, and plasma cutting is just a step up from that and routing is adjacent to that. There can be money in all those things and they all basically use a very similar skillset. The current product im personally developing has me working with open face silicone molds for consumer electronics. Mainly just trying to get away from hobby level stuff and move more into actually using these skills to earn a living. The cash on the adapters was a small taste. Would like to see where I could get if I really started to widen the skill and capital gap.

grey
It photographs well therefore it timelapses well
It prints well (unlike strongy pigmented filaments), like black and white. White also blemishes far too easily, even during the print process. Black makes it almost impossible to see any artifacts you want to remove, and too easy to see ones you cant remove. Both are still good colors in their own way though.
It isnt some garish color that you can only feel right printing some things with

Personally if i was current me advising newbie me i'd say buy 10kg of flat grey, and 10kg of miscellaneous colors. Best value for money, not a huge investment.
Or 5kg grey and 5kg colours if you are a total rookie who thinks $300 is a lot for 20kg of filament.

You are probably going to throw away most of that anyway, so grey is a good baseline, with learning to be had by comparison against the other various colours and opacities/surface types.

Dont fall for the $40/kg of filament because its BeTteR ruse. Unless its carbon fiber or some hybrid that you ACTUALLY need; $15/kg is the right price for PLA and PETG.
>>
>>2794811
>Its a really good printer if you already know what you are doing and have used klipper before.
Just like every other printer /with a new board? Since you already listed more negatives on your own you can see why i rather saw it as "meh", albeit not necessarily all bad.

>>2795331
I'd at least mention ASA in that regard. At least when it comes to bigger prints.

So then stop buying the shit from asshole resellers.
https://www.aliexpress.com/item/1005006064018961.html
https://www.aliexpress.com/item/1005006007948082.html
Theres plenty of good quality cheap filament if you just start buying direct from the source rather than some opportunist who imports the same shit and warehouses it.
Shit, even kingroon is a 1st level reseller, you could always go direct to the factory via alibaba. I've done that before with good results. But minimum order tends to be ~30KG and they seem to always want to charge the highest DHL/FE rate to ship it. Still, some research and waiting a week or three would get you much cheaper filament.
Buying euro "made" filament is your problem. They probably just import and relabel it anyway.

....currently printing chinese PETG from 2018.

There is a door in my apartment going to the landlords part(some dumb rule to avoid paying taxes), and I want to sound proof it, having gotten permission from the landlord.
The door is probably never gonna open, but I don’t want this to be a permanent solution as I want it to be easily removable.

wat do?
>>
>>2794985
Build a cork for the door opening.
-measure inside door jamb
-deduct 1.5" from width and height measurements
-buy a sheet of homasote (preferable) or 3/4 MDF
-cut to size
-wrap in 7/16 carpet pad using spray glue and staples
-now wrap this in short pile carpet, use glue and staples, make the seams neat
-Insert this "cork" into door opening

I've built this to augment the soundproofing ability of various doors over the years...I play music and it gets loud. For my application I've used hinges, but you can probably get away with just jamming it inside the door jamb, if the door handle doesn't get in the way
>>
Similar to the other guys suggestion but less steps and probably cheaper, buy a sheet of rigid foam insulation and cut it to fit in the doorway. You can fill in the edges with weather stripping. I think a better solution would be to put a solid core door in but that's not your problem and you don't want to start doing your landlord a bunch of free favors
>>
>>2795048
I’ll assess if this is feasible, thanks

>>2795055
The door is actually solid core. The sound is already quite muffled but there are gaps around the frame
>>
>>2795055
The secret to soundproofing is mass, and foam doesn't have a lot of that, that's where the MDF comes in. Good acoustic baffles have a good amount of heft to them.
>>2794985
I'm the cork guy from earlier. I forgot to mention mass-loaded vinyl sheet, look into it. I think the cork is the best solution tho if it works for your application. Good luck.

I guess this is not a straightforward process like putting putty on a normal wall due to the more humid conditions.
I don’t need to make it look aesthetic because I want to mount a cabinet over it. What would I need to use? The answers online are a bit inconsistent.

I think I'll cut it off and try to make one of the ones that you mount to a stump
>>
>>2795307
just get a splitting maul, if that's a no-go for whatever reason you step up to a hydraulic press splitting rig on a little atv trailer, and then you get to buy a quad to drag it around
>>
>>2795302
Look up black powder log spiltters. Do weld some log chain to it if you make one since the hunk of chain stops them from flying away.

Boomers have gatekept the trades so hard they aren't even worth pursuing for most. Wanted to drill a water well in Texas in my backyard. You need 2 years of experience under a licensed driller which includes 15 bore holes and 15 pump installs as well as a passing score on the test. 2 years to drill a fucking hole in my backyard. Meanwhile you can be a Jew and take the series 7 and sell financial products to teenagers in much shorter time with zero experience.

Is two years of experience going to keep me from fucking up the water table? Fuck no. If anything pissing away two years is going to make me cut corners. Boomers don't give you any way to compromise. Can't have an inspector come out and license you on the hole you drilled, but you can have someone at the DMV ride alongside you to get your license? Boomers really ruined everything.

Cull clients to large industry only (they're still dicks and treat you as a bank like any shop). My bro got very rich doing repair machining since apparently even German quality has become roach guest worker quality. He's basically rebuilt brand new machines for a tire company because the OEM in Germany gives zero fucks.

He also does stuff like welding cast iron (Crown Alloys MIG wire is glorious) for a local sausage company but now insists they clean everything before he'll touch is because gearboxes full of maggots. (He doesn't eat their sausage after that.)

Just be honest about what you know OP. They probably don't expect much but will have you driving to the store to get parts or digging holes or snaking drains to start. If you lie about your experience they will find out immediately when you're sent to do something by yourself and fuck it up.

Compression lines don't have to be tighter than hell, finger tighten then give it maybe a half turn with your wrench. Drains you will want to tighten with wrenches until you can't get more out of it then test with hot and cold water for longer than you think you need to.
