Prusa Bear Filament Spool Holder w/ bearings
thingiverse
Edited an awesome existing Filament Spool Holder (https://www.thingiverse.com/thing:2846383) to accomodate a threaded rod and bearing system to easier spool filaments. I had to continually spool off extra TPU during printing. With this new bearing system, the TPU rolls off with no tension. While you can source the non-printed parts to completely make yourself, but I used parts from this item on Amazon: https://www.amazon.com/gp/product/B08TM8N77D/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Print with a pause to insert the hex nut, then resume printing. No supports necessary. You can see the seam on my print, as I didn't pause the print properly, so had to print two pieces and glue together.
