This 3D printed mount is a general, multi-purpose mount designed to house the CRICKIT PCB with M3 machine screws. It features slots for attaching to surfaces and things. The low-profile design has openings for all of the various ports and terminal blocks allowing room for cables and wires.

Add-On Attachments The mount is designed to fit various add-ons like for tripods and battery packs. The center of the mount allows for these add-ons to snap fit and lock.
