Ender 2 / Ender 3 Belt Tensioner


Ender 2 / Ender 3 Belt Tensioner

Ender 3D printer upgrade – Belt Tensioner

When I extended the bed on my printer I found I had made the belt slightly longer than necessary, and the Y-motor and stock tensioner were at their limits.

I wanted adjustable tensioners anyways, so came up with this design which has a good scope for belt travel.
