low profile Spool holder (remix of Willi)

 Willi's  Prusa Mini leg extension kit and spool holder is  a great addition to my mini. I use all different types of filament and the original built in slot for prusament spools didn't work well with all my different spools.   Willi's spool holder was just want I was looking for, it was low profile and fit right under the leg extensions.  

I had one small issue with the center of the spool holder; it was designed for a prusament spool.  some of my larger spools would go out of center and fall off the spool holder. 

This remix solves that problem. I removed the bevel from the center on the spool holder. This allows you to use various sized collars to center your spools.   I also made the arms a little longer to help stabilize spools with a larger center.

print my “spool.stl” below 

and

you will need to download and print these parts from Willi's  project:

mini-base-spoolholder-sleeve.stl

mini-base-spoolholder-stand.stl

you will also need the 608zz bearing and  3mm screw ( both can be taken from the stock prusa spool holder.) 

print the needed collar or create your own ( 48mm ID center hole with whatever OD you require. 5mm high) 

I can easily switch spools now and, with the correct collar, I never have to worry about filament spool going off center again.
