@Dobromir it’s a standard hex M2 12mm acrylic stand-off. It’s fixed to the bittle below by a 20mm stainless steel M2 bolt. I carefully drilled out the screw holes in bittle with a 2mm drill and passed the bolts right through bittle’s base. On top, a 10mm stainless steel M2 passes through the 3mm clear acrylic sheet which acts as a back cover, then an M2 acrylic nut acting as a spacer, then the RPi, before screwing into the same 12mm M2 standoff. All these parts are available on EBay.
All clear! Thank you! You took time to make it look pro, for sure I'm stealing the idea
@Rowan this black Pi support, what is it? Did you 3D print it?
Looks very neat! Tagging this post so I can get back when connecting RPi. Thanks for sharing
