Low profile filament spool holder, for when you want your filament sitting next to your printer, and don't take up a lot of space.
Use 4 skatebearings (inner diameter of 8 mm) and press them onto the stud - (if very tight, sand a little bit). These can be found very cheaply on ebay.
Use the screw to adjust width.
Secure knob with glue.
The design should fit most spools - write me a comment if you have any questions or suggestions. Happy printing <3
Parts: Resolution: 0.2 mm - 20-30% infill
Screw: Resolution:0.1 -0.15 mm - 30-50% infill
UPDATE 4TH SEPTEMBER 2017:
The standart screw/base can hold filament spools of 100 mm in width.
I've added a longer version of the base and screw to accommodate user requests for longer screw/base. This allows for 150 mm spoolwidth.
