4 years ago I can't think of a way to mount the stem that wouldn't interfere with this, since even if it's on the top the light won't shine through where the stem is underneath, but it would be cool. If you have a lithopane already, you could use the artisan functionality to place it at the top of a keycap right now.
Another option for 3d printers with good bridging is to place the lithopane inside of the top of the key. you don't have to do anything with the stem and you can't see any part of the lithopane until you turn on the LED. You'd have to tweak a lot of things to get it to work, but it's definitely possible
With RGB gaming keyboard being the de-facto standard for gamers, I thought it could be cool to support litophany in the library.
This would be achieved by "carving" the symbol on the keycap on the underside of the top surface of the keycap. However, because of the stem being there, a different joint between stem and top surface (with a gap) should be engineered.
Alternatively (but less cool!) one could bypass the stem problem by having lithophanic symbols on the front (vertical) face of the keycap.
Just an idea. I use a blank keyboard (no symbols on it) to do office work. How cool would it be to switch on the RGB at night and having the same innocent keyboard turning in a badass frag-ready FPS gaming machine? :P Clark Kent meets Stella Pajunas-Garnand!
