C7 Style LED Pixel Cover with Nubs

thingiverse

My first thing post... This is a remix of Lithgowlights C7 cover at https://www.thingiverse.com/thing:892479 which is an excellent design. David's height/width ratio looks natural to me (not short/fat/stubby) and fits nicely compared with other C7/C9 designs out there. While they fit snugly around a 12mm pixel, I wanted to keep them all uniform depth and also be able to use these when mounted to Boscoyo strips, I added nubs to the inner 12mm rim that will catch on the 12mm pixel groove. I used the nubs from keith204's thing at https://www.thingiverse.com/thing:3331268. I pulled it into Slicer and ungrouped the model, overlayed the nubs with Lithgowlights C7 model. I also included a 3mf Cura file with the model laid out in an 8x8 grid for 64 printing at one time. It was made for an Ender 3 or 230 x 230 bed size.
