Outlet Box for 1 and 3 gang

thingiverse

I tried another 3 gang box and it cracked when installing it. I drew this up to be a little more robust and have slightly larger screw holes to not cause cracking when screwing in. 2.2 mm thick wall. 2.25in deep and punch out holes. Try not to hit the punch out holes before scoring with a knife or run a drill bit around the hole for easy hole knockout. Update 1/20/2020: Added Single gang box Update 2/3/2020 Learned a lot about PLA since I made this. I recommend printing this with PLA + or PLA Pro. The PLA + handles stress better without cracking. PLA + will take hammer hits and drilled holes without cracking. Also, try printing with a larger nozzle. The larger nozzle lets you print this thing in only an hour or 2 and get you back to work. Just some tips in case you are new to printing. PETG another good option, probably the best option. PETG has another learning curve but worth it if you print function things.
