Raspberry PI 3B/4 Enclosure

thingiverse

I use Octoprint to control my pair of Ender 3s, but having a Raspberry PI floating around at the mercy of its cables is annoying, so I created this enclosure and optional bracket so that I can stick it to the side of the printer somewhere.**Updated: Better bracket. Alternate base for direct attachmentIf you need a case for a PI Zero, I have a similar enclosure for that here:https://www.thingiverse.com/thing:6413406PrintingPrint on of each model3b-bottom.stl - The bottom of the enclosure. Print flat, no supports needed3b-top.stl - The top of the enclosure. Print flat without supports3b-bracket.stl - Optional bracket that fits a 20m V-slot extrusion and clips around the enclosure3b-bottom-2.stl - Optional. Alternate bottom. Print this instead of 3b-bottom.stl along with foot.stl to attach directly to the V-Slot extrusionfoot.stl - Optional. Foot for attaching 3b-bottom-2.stl directly to the V-Slot extrusionI printed these parts in Inland Tough PLA, but you can use whatever material you have and/or like.Additional PartsBesides the prints above you'll need the following additional parts4x 20mm M3 screws (and appropriate driver)4x 5-6mm M3 brass insertsA soldering iron for getting the brass inserts setOptional: For attaching Foot.stl to 3b-bottom-2.stl2x 6mm M3 screws (make sure the screws don't touch the bottom of the PI board)2x M3 nutsAssemblyEnsure all prints are clean and have had any printing artefacts removed. Place the Raspberry PI inside the top (3b-top.stl) and screw the screws through the hole so that they just come through the screw holes in the PI board.Put the bottom (3b-bottom.stl or 3b-bottom-2.stl) in place and carefully advance the screws making sure you don't get them cross-threaded.Tighten the screwsOptional - Mounting The BracketTo mount the bracket (3b-bracket.stl). Find an appropriate place on your printer that won't interfere with its operation and slide the bracket in place. Now slide the completed enclosure into place.Update: Print 3b-bottom-2.stl instead of 3b-bottom.stl, and foot.stl to go with it. This will allow you to fasten the PI enclosure directly to the V Slot extrusion instead of using the bracket.Enjoy.
