3Dfused y Axis Linear Rail Tensioner & Idler Holder
Description
Since I didn't like the original design of 3Dfused linear rail belt tensioner, I modified it to my needs. I added arms to the tensioner, so that the pulley holder doesn't rotate. The original idler holder is letting the pulley scrub the holder, so I added some space to put 2 nylon washers between them. It can be a bit tricky to put the washer, you can glue them down if needed. The overall design feels much more durable now and the idler is free from friction. You'll only need 2 nylon washers for M5 bolts (12mm OD, 1.5mm thick), all other hardware is included in the kit (my design uses the same bolt length as the original design)
