My friend wanted to put some Monster® stickers on his spinner caps. I told him I could 3d print the M logo into the caps so they wouldn't wear off. :D
Edit: Added new cap design which fits easier and better. Added Fusion360 source file. Changed License to Public Domain. Source for my better cap design is my thing located here: http://www.thingiverse.com/thing:2130642

2 color printing obviously.
I printed up to .30mm in black, paused the print, and printed the rest in green. The M cutout is .5mm thick. I had the last layer of the cutout print in green to make the M stand out better. Enjoy!
