Collector's OCD xD must collect one of every type. so cartesian (corexy, Cube shaped and Cr-10 T shaped), Delta type (Normal and inverted), Scara type (RepRap Helios), Straight Line Type (the Kappa 3d printer), and well Polar type, which I'm probably will not get because no headed bed is a big minus for me.

on more serious note, even though I am a full time teacher, I have time (since I'm single >.>) I will probably have some of them be on 3dHubs or Makexyz, for extra income, that way I can have some printing what I need for my own business and also for others for that extra income, and also because I enjoy it.
