Spool Roller

thingiverse

**Update 3/23:** *Per a user request I've added a large version of the spool roller to accommodate 3kg spools (270mm dia x 104mm wide). **Update 12/13:** *Added a self-centering roller. The new roller has a concave profile that should keep the spool centered on the rollers. Although the standard rollers are working just fine, I decided to try to step up the design a little.* This is yet another spool roller. I am currently printing with [Ultrafuse 316L Metal Filament](https://www.matterhackers.com/store/l/basf-ultrafuse-316l-metal-composite-3d-printing-filament-175mm/sk/MRDKJRRS?rcode=PPCADS&gclid=CjwKCAiAxMLvBRBNEiwAKhr-nIEDKaDHOJNrqssnExwD5cAWkd7OscF5hf6Mf-BXkP_NWNsaXPwiVxoCKRIQAvD_BwE). A spool weighs 3 Kilograms. I tried printing using my standard spool holder. But, the heavy spool applies too much weight on the holder. The excess friction causes extrusion issues. I looked on Thingiverse for a spool holder, but found they required parts that I didn't already have kicking around; ergo, I designed my own. Parts required to complete: - 4 [M6 x 16mm screws](https://smile.amazon.com/gp/product/B07636PR9Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - 4 [626 Bearings](https://smile.amazon.com/XiKe-Pre-Lubricated-Performance-Effective-Bearings/dp/B071JTPQN6/ref=sr_1_1_sspa?keywords=626+bearing&qid=1576077596&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyTU1HWEtQMFMzRUpUJmVuY3J5cHRlZElkPUEwNDcwNzkzMkdYOFhZSVRDUlFYUCZlbmNyeXB0ZWRBZElkPUEwNTA2NDQ3M040TU9GUTFPWFZTTiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=)
