Brackets designed to fit my Raspberry PI Zero 2W Enclosure model:

The Models

• Bracket - Designed to slot into a 40mm V-Slot extrusion without the need for any additional hardware.
• Bracket2 - Has “feet” that will slot into a 40mm V-Slot extrusion, and has a screw hole so that it can be attached using a screw and a T-Nut (I just used some spares that came with my printer). This is useful if you want to mount it somewhere without needing to partially disassemble your machine.

In each case, the PI Enclosure slides into the bracket and should be positioned to allow for connected cables.

Printing

• Bracket - Print this one on its side, no support are required. I printed it in PLA with 0.2mm layer height and 20% infill.
• Bracket2 - This one was more tricky to print. Print upright with supports touching print bed. Same settings as before - 0.2mm layer height, and 20% infill.
