Spool Caps (STEP files, Fusion Source for Custom Size)

Along the same lines as Adam's remix, this give you high resolution STEP files (vector curves) so the X1 can print arcs instead of many-small-line circles. Mostly includes some small tweaks from Adam's variant for 0.2mm layer optimization.

Additionally includes the Fusion source file so you can edit the size through parameters to whatever sized you need for your spool.

Printing Recommendations:

Optimized for 0.2mm layer height, 4 wall loops (to prevent infill printing in the upper section) and 99 top/bottom layers for a solid print.
