Not seen a home brew one yet. I need one too. Infact I used to do A LOT of home PCing. It is a mess somewhat but not bad. But I hate wasting perfectly good powder. I will set up and be powder coating in my shipping container if I ever get it cleaned out.

Built this one out of melamine. It is smooth and easy to clean up overspray. I put a 3" hole in the center of the floor to sweep excess powder into a funnel mounted underneath, the funnel runs it into a coffee can. I don't worry about re-using the excess powder but I suppose you could sweep it up and re-use it if you wanted to.
The top hanger bar is just a pc of angle iron with a bunch of holes drilled in it to allow using wire hangers or S hooks.
As I recall the spray area is 24" deep x 36" wide. Simple 2x4 legs and frame for the "box" to sit on. Height depends on what you want. For me it was I think 40" to the bottom of the box. Backsplash and sides is up to you too.

What's melamine?
I think something like that would be perfect for me, it needs to be no larger than the oven I use.
How do you like that gun? Easy to use? Easy to clean?
It's kind of a pain in the *** to keep grabbing my air hose and adjusting the pressure before getting ready to spray.

It's particle board with a smooth finish already applied. Really easy to clean up.
The gun I use is from Summit Racing. It really is a nice entry level gun. Easier to use and cleanup than the Eastwood gun, (which isn't too bad). I too got sick of adjusting pressure all the time and having the heavy air hose hooked up too. This one has its own built in air supply.
To aid in cleanup I ordered extra powder cups and keep each color in its own cup. Makes color changes that much faster too.

I have never sprayed powder but this is the fundamentals for a booth.

Kind of a waste of time unless you are reclaiming powder...
If that is your effort then simply put down a plastic drop cloth to catch the fallen powder.
If just to keep the area clean without reclaiming the powder just vacuum it up with the shop vac...
If you are getting that much powder on surrounding stuff spraying little parts inside a box then you are using WAY too high an air pressure, the stuff should come out like smoke...
My biggest complaint is that there is a lot of wasted powder on the fixtures and such.

I went a little bigger scale and built a 8x8 "room" out of PVC conduit and plastic sheeting. Added a box fan and house air filter for ventilation. Use it for everything from PC to spray paint. Just added a dedicated air drop in the room with a reg, next step is table for mixing paint and more lighting. I use the **** out of it and am considering making it more permanent. Really want to find some cheapish floor grating so I can have a true down-draft.
Basically just a "Bigger Box" then.
Just use a respirator for your lungs, no matter what you are spraying.
Powder only really requires a particulate filter.
I don't think I even use THAT much pressure. BUT it depends on your powder too.
Make a box use the white face melamine material, it is not particle board but Masonite. in the TOP of the box put a Shop light and a diffuser sheet. (spreads the light) Make this box with the bottom at a comfortable work height.
about 2' deep and 4' wide and 3-4' high Make the "Front" side open so you can work and large enough so you can easily get parts in and out.
and turn them around so you can coat them completely.
In the BACK of the box make an opening that you can fit a couple 20x20x1" HVAC filters in and use a box fan outside that drawing OUT of the box...

Similar to this....
Just make sure you build it big enough for the largest item you plan to coat.

yep, built mine similar to this. used the same material but only made a cutout for 1 box fan. The cutout was sized to fit a furnace filter so the fan behind it draws the unused powder into the filter. I might cut a hole in the bottom for reclaiming, not sure yet. I can take pics later if you want but I just used 4 2x2's as legs and a melamine shelf underneath

If you're getting that much overspray while using such small PSI then you've probably got an issue with your ground cable.
I haven't used a spray booth in years and have a wrought iron security door turned into a horizontal rack suspended on my ceiling hoist like a swing stage -- I can use it as a table or hang items from it on wire.
I prefer 360-degree access and wouldn't use reclaimed powder if ya paid me to -- there's just too much opportunity for errant dust, cat fur and pollen to end up in my results on the high end work I do ... and rework is just too costly to chance it.
