MPCNC Primo Nema17 drag chain mounts
thingiverse
Drag chain mount for MPCNC Primo, remixed from thing https://www.thingiverse.com/thing:4613811. I chose to attached the drag chains directly to the Nema17 steppers. The drag chains i used are Sunhokey 15x20mm, purchased from https://www.amazon.com/gp/product/B07MJPBV4Y. I needed four of them since i have a larger machine (3x5' footprint). For the drag chain from the gantry, I used a simple aluminum angle to give the drag chain some support to rest on (it's ok if it's only on one side). This was inspired by https://www.thingiverse.com/thing:4635424 but created from scratch for my application. Update April 16, 2021: added J and F size clamps.
