608 Idler Pulley with Stand

thingiverse

The 608 Idler Pulley is designed for a standard 608ZZ bearing with a center groove diameter of 25mm and an outside diameter of 30mm. It can be secured onto the bearing using M6 nuts, and more information can be found at [http://bit.ly/1bbeXHQ](http://bit.ly/1bbeXHQ). An update to the model has been made to reduce the need for supports during printing. Additionally, this pulley aligns perfectly with Gineer R&D's stepper motor threaded drive pulley at the bottom for parallel lines. For added guidance, you can also use [https://www.thingiverse.com/thing:2609737](https://www.thingiverse.com/thing:2609737) as a side guide for keeping materials centered. The guide uses the same 6mm retaining shaft as the original pulley and stand, and an extra 5-10mm should be added to the shaft length to accommodate the guide.
