Filament Spool (Adjustable Width)

Used this as a learning tool for Fusion 360. Intended use was just for the filament samples sent with the printer. Now I am using them once a spool starts to run low, saving space within the filament box for more to arrive.

I printed in PETG with standard settings, probably set the infill to 10-15%. In order to change the overall width I have labeled the Extruded feature "Spool Width" (just before Threads were added) in order to make any adjustments to the width of the spool. Reversed threads (just because) are a good tolerance, clean them a little before assembly, also work back and forth a few times. Inner spool width is +3mm to the 15mm or 35mm if printing the .stl
