OverlapStrap Z Skates

I have built the first of the Z skates for OverlapStrap.They can be tightened using the 4 M4x40 bolts, and when tightened just right they run very smoothly. I haven’t had a chance to upload any drawings of the parts that make it up yet.

This image gives you an idea of angles at which the bearings are arranged.

  1. I have used a similar approach for my z-axis. Key difference is that instead of a rod, I'm running the bearings along another aluminium angle. It also runs smoothly and seems to be quite stiff to resist lateral movement
