Keycap Logitech MX Mechanical - Đủ Mọi Kích Cỡ

The original model was perfect for the 92 base size keys, but the other 18 keys all had additional sizes. Popped off measured and tested all of the other sizes and they all fit and work. Caps was the most tricky, but what Ive got here fits just fine.

Unfortunately no good way to get that nice top curve from the original caps when using two colors so I didn't  try modeling that in.  

Print at 0.12 or less layer height for best results. 0.4 nozzle or less recommended. I let it print at normal speed and didn't have any issues but I think a little slower might be best for the dual color printing I show here.

If you need the mathematically sizes keycaps I can look into it.

My test were all done using 2 color printing on my Bambulab X1C. The lights are always above the center of the key so you need to position the color element where it will be lit for best results. I always cut out the letters, then put them back in and paint them in the slicer using the bucket tool on the top and bottom so the color goes all the way through. I thought I would need see-through PLA, but the solid red PLA I used lights up pretty good too.

I did not upload the keys with the words\letters in them. If that is really desired, I can look into it. I think I need to make some adjustments in font and sizes to fit best, thought I'm happy enough with most of these. (not sure what happened to space and Numpad enter could be cleaner)
