[GreenKeys] 3d printed keytops

[E.]

Here is a video of the process (below).  Looking at his CAD schematic, it almost looks like there would be have to be a spring?:

Also he made some other parts, like the platen crank handle.  Some of this would be pretty valuable, as I’ve heard — and I could be wrong — that Mr. RTTY has run out of some parts.  With the key tops, vinyl lettering could be made and placed on top.

It’s a pretty interesting idea!… better than nothing for sure!
