Spool Rollers for Folger Tech i3 2020

thingiverse

If you have a Folger Tech i3 2020 printer, notice that the rolling friction on the spool may sometimes be a bit too high. This can cause the extruder wheel/gear to slip slightly and create gapping issues if the filament tension is too tight. The existing design from Folger generally works well, but for those pushing print speed to its limits, ensuring minimal friction rolling for the spool and lowest filament tension are crucial. Here's a part that prints two of and fixes this issue simply. Two 623ZZ bearings per roller are needed; one kit usually comes with extras, so use those instead. Print two identical parts since you'll need two for the upgrade. This setup works universally with various spool types/widths, making it easy to adjust by moving the outer roller as needed, regardless of your spool's width.
