Update to my Lazy Grid Clock: https://www.thingiverse.com/thing:3241802 (v1 removed from thingiverse.
Note: Just uploaded/imported this to prusa printers to try and get a feel for the editing capabilities here... so layout/images/whatever might change. And if I saw that correctly .INO files don't get imported, so you'll need to have a look at the instructables/thingiverse pages from this one to get everything.
Basically the same as before. But I've decided to remove some options (variable diffusers and such) and concentrate on making printing and building this easier.
The LED grid itself is the same, so are the electronics. So sketches running on LGCv1 should work out of the box on v2, there's some remixes out there.

Walls are always multiples of 0.5mm, so I strongly suggest using and extrusion width/line width of 0.5mm (no, not recommending a 0.5mm nozzle here!).
