Filament Spool Spacer

thingiverse

Here is a simple star-shaped spacer for filament spools mounted on a 32mm aluminum pipe in a dry box. I placed my spools on this pipe, and to keep them separated by 1cm (Z-axis), I designed a small spacer with dimensions approximately 80mm in both X and Y directions. The long arms of the star shape ensure that the spacer won't slip into the spool, even though its inner diameter is about 33mm - just the right size to fit snugly on the pipe. Printing this design takes around 50 minutes and uses roughly 3.5 meters of filament.
