Raspberry Pi Zero box designed for Plastic Inserts and M2.5 screws.
The Fasteners that I have used are PSM Heat-Lok. I use my soldering iron to insert them, in this design is a bit difficult as some section of the wall housing the insert are thinner than usually recommended.
Your printer must be cable of printing solid walls of 1mm thickness.
This design can easily be modified for self tapping screws, allow access to GPIO connector and better ventilation.
The author marked this model as their own original creation.
