I'm lucky enough to spend my life making robots for medical research and the arts. The pen in my profile image is held by a trashed industrial robot I rescued and repaired.
I laser cut thigns pretty much every week for my work and get things 3D printed on high end machines every few months, but those things are all very specific research tools. The stuff I'm sharing on here are the bits and pieces I make outside of work.
