Yazzo Disc Axle

My Delta Bot needs a "knee". that's the joint between the driving motor, and the "ankle", which is the lower leg of the two legs of the delta bot.

This thing is a simple "knee". It has a notch in it so it can be easily connected to other things that have the matching "key".

You simply slip a piece of smooth rod, or dowel, or whatever you have that can rotate within the hole, put some bar ends on the axle (like a Clevis joint), and you've now go a knee!
