Universal Spool Holder Adapter for Mendel90

thingiverse

I use the Nophead's Mendel90 design spool holder (https://github.com/nophead/Mendel90) with multiple spool sizes, but it's limited to one size, so I created a universal version that works seamlessly. It employs the same hardware as the standard holder and replaces the bearings for effortless installation. Any spool up to 100mm wide can be easily accommodated without adjustments. This solution has worked flawlessly on my Mendel90 spool holder with a width of 69mm, but if you need different widths, simply scale the roller to fit. The extra width poses no issue as I've found that the spool holder stays securely in place using only the top hooks on the frame sheet without needing the bottom screw.
