Upgraded axle shaft

This is a much better roller shaft for the laser engraver. The kit provided little more than a heavy duty straw. Which, even when tighten was loose.

These pictures are of the laser head, but I also installed them on the Y rails.

It's designed for the widely available EleksLaser A3 Pro laser engraver kits (mid 2017), from online retailers; Banggood, GearBest, EleksMaker and eBay.

I need to fire my maid, so much dust and fibers. :)
