Raspberry Pi3 2020/3030 Extrusion Mount

thingiverse

This is a straightforward design to attach a Raspberry Pi3 to a 2020 or 3030 aluminum profile. It's advisable to print four spacers using the M4 spacer template, scaling it down to 75% for an M3 size in both X and Y directions. Set the Z height of the spacer to 4 or 5mm. You'll need four M2.5 bolts with a length of around 10mm, along with four M2.5 hex nuts. Alternatively, you can use two M5 8mm cap head bolts and two printed M5 T-Nuts (you can find these designs on Thingiverse for 2020 or 3030 profiles). This design has been successfully used to mount the Pi3 onto both 2020 and 3030 aluminum profiles. However, I've only tested it with these sizes and haven't tried it with a 4040 profile. When printing the mount, face it downwards with the lip and brace facing upwards.
