These are Mr-What's tweaks to Johann's mini-kossel drawings circa Feb. 2014. The main changes are:
-
Attach the carriage to a base that can mount Delrin wheels that ride directly on the extrusion, instead of the linear bearing rails.
-
Added support material to make printing easier on Quelab's public RepRap printer (Hackerspace in Albuquerque, NM)
-
Simplified some parts.
-
Changed effector head to carry a different shaped hot-end.
-
Attempting to use pressure sensors on top of the NEMA-17 motors instead of the probe. This will require new, very tight tolerance print bed mounts.

Johann offers some free printed parts, on the condition that once you get a printer working, you give away two (2) sets of free parts to others. After that, you are free to sell printed parts.
