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.
