CR6 Roller Spool

prusaprinters

<p>I moved my spool holder to the top of my CR6, because I upgraded to Direct Drive. &nbsp;When using TPU, I noticed that the filament did not feed very well on the stock spool holder. &nbsp;I designed and printed this one, and it is working great so far.</p><p>I used these bearings: &nbsp;<a href="https://www.amazon.com/gp/product/B07TQ6NHWN/ref=ppx_yo_dt_b_asin_title_o06_s02?ie=UTF8&amp;psc=1">uxcell FR8-2RS Flange Ball Bearing 1/2"x1-1/8"x5/16" Shielded Chrome Bearings 4pcs: Amazon.com: Industrial &amp; Scientific</a> from Amazon.</p><p>The bearings were a press fit in the roller shell. &nbsp;Install the keeper using a 3mm x 8mm machine screw, it will self-tap into the mount. &nbsp;</p><p>Print the mount using a high infill and 4 walls for strength. I printed this piece using supports everywhere, twist part down. &nbsp;Light supports (8% support in Cura) are all that is needed.&nbsp;</p><p>The mount is a tight fit in the stock arm. &nbsp;I had to use pliers to rotate it, but it has held up nicely.</p>
