Formally the owner of avionics (EFIS, FMS, etc.) and video game design (Tetris, Robocop, Predator, Michael Jordan in Flight, and a number of others) firms, I'm now retired, but enjoy designing and printing / machining mechanisms using 3D printers and CNC mills and lathes. I've used a MakerBot Replicator 2 for 3 years with much success (albeit highly modified), but I've transitioned to an Ultimaker 2 + Extended and a dual extrusion Ultimaker 3.
