I've not had much time this week for the machine and I'm still waiting for the belts and openrail to arrive so I have made the front idlers, both stepper motor brackets and the handle.

This is made so it goes bearing, washer, GT2 pulley and nut.

The handle is a pretty simple design:

and the stepper bracket I laser cut from 3mm black acrylic.  I used the laser but it can be made with a drill press easily but I need an eye test!  Pictures to follow because the camera battery just died.
