Modular Raspberry Pi Mount

thingiverse

I'm using a Raspberry Pi in my latest project and I've been searching for a suitable mount. I don't want a case because I need access to the GPIO pins, and I'm not entirely sure what else I'll be adding yet. I will be using the camera and probably adding a few buttons and maybe some lights. There are many cases available on Thingiverse, but none of them seem to meet my requirements exactly. So, I'll make my own mount! Hopefully, others with similar needs and constraints may find this useful too. This custom mount consists of the base and add-on pieces for the camera and some stripboard for prototyping. I've included a picture of the mounting dimensions for those who want to create their own custom add-ons for servos or sensors, etc. Each of the add-ons has relief to access the SD card when mounted on the front. I use a 0.3mm nozzle for smaller projects like this one, although 0.4mm will probably work fine. Print the parts in PLA or PETG (I used PETG) at 50% infill, and after cleaning up with a knife, run through each hole with a drill. Use 3.5mm for the countersunk assembly mounting holes, 2.5mm for the pilot holes for the countersunk assembly screws, and 2.1mm for the pilot holes to mount the Pi and the stripboard. The countersunk assembly screws are 3.5mm x 8mm woodscrews. These are used to secure both the base to a mounting board and also to secure the add-on pieces. They're a bit overkill to secure the add-ons, but they're cheap and readily available from DIY stores. Use M2.5 x 8mm machine screws to secure both the Pi and the stripboard. Place a washer under each one and let them self-tap the holes. For ease of use, I've chosen to print small plastic posts to mount the camera. This allows for quick adding and removal, although you might need to trim a bit with a knife depending on how accurate your printer is. If you want something more solid, trim them off with a knife, spot the centre and drill out to 1.6mm using some M2 x 8 machine screws. The stripboard mount is sized for a standard 0.1" pitch, with the mounting dimensions being 1" square. This size is small enough not to make the whole thing huge while still being useful for buttons and LEDs, etc. I've added a Pi logo to give it a more professional look. Hopefully, someone finds this useful - leave a note in the comments or send me a private message if there are any issues. Happy building!
