The first round of 3D printing took place last week! The first thing I noticed was that I would need to make my keys substantially thinner if I want them to look more realistic. 

The bearings and magnet design worked well because the components fit right in. I am having some issues with getting the bearings on the rods, however. I also still need to figure out how to get the keys/springs set up onto some sort of base plate in order to show the keypress effect.
