An experimental two-high spring dampened reversing roller cold end for a Bowden cable system. Uses modified Tetrix spur gears and axle hardware. Filament enters and exits on a 30 degree angle to assist in better hose curvature. Uses spring dampening system to allow deviations in the 3mm plastic filament diameter with an adjustable bottom out feature for decreased potential slippage. No bearings or moving plastic componentry.


UPDATE: First prototype made; needed extensive modification/machining for assembly+operation. Need to modify design to remove extra machining steps.

Still in preliminary testing. For all I know this design might not work. Will update page once prototype is manufactured and tested.

It definitely looks nice. How's it working?

Thanks! It's looking promising, yet has an issue with retraction/extrusion rates. I need to spend some more time working the kinks out; I just haven't found the time yet. I will post pictures to my flickr when I do. http://www.flickr.com/photos/wileyb-jhttp://www.flickr.com/photos/w...

Awesome work - would you by any chance have the Tetrix part numbers? I'm lost searching for parts, 'specially the axles...

Thanks a lot John. I added tech specs to the BOM off the Tetrix website.
