3D Printed + Lasercut Prusa i3 (MK3 MK2 MK1) Enclosure

I use a lot of Nylon for my combat robot prints and thus I needed an enclosure to prevent warping. I wanted something simple, lightweight and removable, and with an easy to access door. I ended up using 80/20 hinges for the door, and acrylic which I lasercut for every single panel. All panels are joined using 3D printed brackets and 1/4-20 x 3/8 screws. It's a bit floppy with 1/8" (3mm) acrylic but it definitely gets the job done and looks good too! (https://bit.ly/Qt20Screw)

I've included the Fusion files for the brackets, DXFs for al laser cut panels, and here is a link to download the entire CAD model for the full enclosure if you wish to modify it. https://a360.co/2WJzDTU

Be careful with the screws, do not over-tighten or it will crack acrylic or polycarbonate. I made that mistake with one panel. Oops...

I also designed a spool holder that takes 1-inch PVC pipe, but I generally print out of a DIY dry box so I don't really use it. I modeled some 1/4-20 to straight shank pegs and tried using those on the spool holder bottom to make it hot-swappable, but the thing will lean to one side unless there are two roughly balanced spools on it so I recommend just screwing it to the top panel if you want to use it.

Print instructions

All printed components need sufficient walls and small enough layer height for the printed threads to be usable, so I'd go with .1-.15 layers and 3 or 4 walls. Infill is less important, >15%. All parts print with no supports.
