This remix adds the ability to use a zip tie to tighten up the mount. I liked the design but thought it was a bit loose. Since many of us have extra zip ties left over from building our printers, this remix just uses a single left over tie. I printed this in PETG but I suppose other materials may work as well. Slip the guide over the spool holder then insert a zip tie through the slots in the back. Snug up the tie and snip off the excess. I printed this on the MK3S but it does fit on a Mini if you prefer. No supports are necessary.

 

I  included a Step file and a Fusion 360 file so feel free to make additional changes if you see the need. I'll be interested to see what others may come up with.
