Improved Tensioner for 3Dfused Rail Kits

by Thingiverse
Last crawled date: 4 years, 3 months ago
The idlers included with the 3Dfused linear rail kits are wobbly and twisty, and the idler they include grips the GT2 belts too tightly causing the belt to twist and walk towards the outside of the idler. This can introduce backlash like artifacts.
These idlers beef up the anchoring by extending the anchor piece to capture the tensioner piece, preventing all movement except for the direction it should move. It also re-uses the existing CR-10s smooth idler (the two smooth lipped bearings stacked together) to eliminate the belt twisting/walking problem.
Hardware required:
1qty M4 bolt that's a little longer than the 3Dfused included one, you can probably rob this from the parts left over from your upgrade to rails.
2qty M5 bolts that are 5mm longer than those included by 3Dfused.
Source files:
As always, I have included the F3D files if you'd like to mod this for your own setup. Enjoy.
