Z Axis Holder for Igus Bearing

This is based of Scot 3D's HEVO design.

I modified it to be able to clamp the Igus RJ4JP-01-12 bearings in. Each bearing can separately clamped with 2 screws.

The problem with Igus bearings are if they are not precisely aligned, they will stick to the rod.
To avoid this, I put the holders for 10 minutes in the oven by 75°C with the rod inserted. After that they run perfectly smooth.

Update: Added a Version with Bearing grooves for better grip.
