To support mounted access to the micro:bit the plate can be mounted as needed using velcro to flat surfaces. It also supports camera mounts using the additional camera mount connector (using a tree nut insert) designed by Makers Making Change. The connector requires the insertion of M3 bolts within the holder and fastened with a nut on the back. The mount can then be screwed onto standard camera mounts.

The micro:bit slides into the bottom clasps and the two two side clasps are inserted.

* This is a first draft and I would love anyone with better design skills to improve on this design and share on. I'm attaching the Fusion file if you are so inclined. 

Update: Thanks to PrintLab's easy to learn tutorials, I made a version using dovetails to attach the top clips. They are in the Dovetail folder.
