The Prusa Mendel build is finally complete! Here’s a Stanford Bunny:

PLA bushing sliding on precision ground 8 mm rods is actually quite smooth movement. I don’t think it can go as fast as the original Sells Mendel (which was ball bearings sliding over the rods), but it’s only half the printed parts and the z-axis is much smoother motion too. I will try oiling or greasing the bushings to try to get smoother and faster motion without losing steps. So definitely some tradeoffs but overall a super awesome bot. The Prusa is also fully parametric and entirely made from OpenSCAD. All sources are available on github FTW.
As this is the first bot I built that I actually own, I named this awesometown after my HS science teacher, Mr. Sloate, who really got me into Biology and now, robotics for Biology.
What will we print next?
Awesome! There is spray graphite in the cabinet if you want to try that.
