Excellent work however, as Walter stated, we need the tabs. Something like the original plastic blanks.
Cheers

Re: Overlays!
I've heard from Michael today that there are no tolerances applying to the dimensions of the overlays. That's an information in contradiction to my industrial experience of some decades but he continues claiming it.
Well, I inspected the six slots on my DM42 Beta using a thickness gauge and found them being 0.5 mm high. Please crosscheck - maybe we can convince him based on some statistics.

Re: Overlays!
I'm using 0.35mm thick cardboard.
I removed the 2 tabs in the middle because it's a little tricky to get the tabs into the little holes: the keys are too close to the edge.

Re: Overlays!
Here’s a version with tabs. I cut one of these from card, and it’s a very tight fit into the tab slots.

Re: Overlays!
Has anyone made their own Overlays using a 3D printer at all please?
