What’s the catch?

So i want the add on boards to be able to be swapped without tools. The normal method of securing M.2 cards is with a screw, but that is easy to loose, and needs a small screwdriver which can be fiddly.

My original plan was to have some little clips which would hold the board in place. The clips would be removable and replaceable in case of damage.

The clips were included with in the last print, and they sure were small!! I wanted to get the mounting system sorted before spending too much time on the add on boards themselves, so i printed a dummy board for testing (please excuse the fuzzy photos)

While the clips do work, they are super hard and tricky to unclip.

So with some thinking happening, I have come up with another plan

The add on board would of course need to be tweaked to move the cutout to suit, but i think it might be a better solution

Might need some more thought/polish, but its already looking like a better solution…
