Summary

I really love DavidM's Stream Cheap Mini Macro Keyboard but decided to add another cover on top of the faceplate to hide the keys and the screws.
The cover is suitable for 18x18mm keys

Update:
cover2.stl adds a little more space to the keys (0.25mm on each side) as keys sometimes got stuck. The squares have rounded corners for a cleaner look.
Additionally it's now narrower regarding the hole for the screw head (with the ones I used it's now a press fit)
