Pi3 Modular mounting plate

thingiverse

I designed a mounting plate, measuring 75mm by 100mm, and only 5mm thick. It features 1.5mm standoffs carefully aligned to accommodate a Pi3 with extra clearance on both sides for connectors. This design should be straightforward to upload into Tinkercad, where you can easily add pieces to create whatever you need. I used simple 3mm through holes and recommend using long bolts and nuts for mounting or heat-setting threaded inserts directly onto the plate. Alternatively, you could drill smaller holes and tap them by hand. I reworked the model with 3mm standoffs in mind. However, when I used this version with my Pi2, it hit the bottom of the USB and Ethernet ports before the standoffs made contact with the board due to their 1.5mm height. For reference, I've left both versions up – you can use either one depending on your needs. To create more space for connectors, a relief cut in the flat plate is also an option.
