I have added the libraries in the files, for directions on how to use see the original thing.

I have the MK3S and MMU2S, the original setup took up way to much space. so I set about using the shelf under my desk to locate the 5 spools. there were many iterations and failures, but this arrangement works the best.

I modified the spring of the universal rewind spool, so that I could use a threaded rod and it could catch on a hex nut. the scad files are included. So you can modify the spring to your heart's content. I am using the 2mm version of the spring to make it stiffer. the current spring model works with an 11mm or 7/16 turnbuckle nut on a 1/4-20 threaded rod available at your local hardware store.

the extruded aluminum I ordered from amazon, I don't remembe
