Smart for 2 Key buttons

##Description:

Replacement buttons for smart for 2 (old model). I have uploaded 2 versions one with raised icons and one without.

I used a 0.3 mm nozzle for the result you see and the print was done in roughly 30 min. Don't use adaptive layers and definitely use normal supports unless you want to print 3D noodles :)

##EDIT: I noticed that I had the Lock/Unlock icon positions mixed up, I have already uploaded the new "repaired" version :)
