Mini Master Spool

This is thing:
https://www.thingiverse.com/thing:2798914

I have absolutely done nothing to this and contributed nothing to this thing,

I'm only providing the STL
The original creator only uploaded the STEP so used an online converter
( https://www.makexyz.com/convert/step-to-stl ) and uploaded here. thats it.

EDIT: the bottom wouldnt slice properly for me in slic3r. I used https://service.netfabb.com/service.php to fix the file.
