thingiverse

Here's the deal. We're upgrading our predecessor with room for a 608 bearing and adding a slot in the process. From now on, we're cutting out rounded details instead of hexagonal ones. The spool change just got even simpler: no tools needed whatsoever thanks to our nifty nut thumbwheel feature that came straight from the customizable edition. I'm counting down until more bearings arrive so you can check out the visual evidence.
