Spacer for filament spindle

I got problems with smooth unwinding of filament. Spool was to heavy to rotate when was just hung on a thread. I needed to make distance to move axis of rotation to center of spool.

Ready stl file is for Internal fi=66mm, spool width=58mm

SCAD file is ready with parameters - d & h - for spindle internals.


Remember - you need to print two of them!
