Reusable filament spool made from a single part printed twice. I always forget how much a spool weighs so the SPØØL the weight printed in it and it does not roll away from you. Still it spins freely enough in my filament dryer. 

There are 3 versions, 190 gram with space for a label, 190 & 180 gram without space for a label.

Use your slicer software to get as close to half of the weight on the SPØØL. 

Tested with 3DJakes ecoPLA Refill  700 g and Fiberlogy Refill Easy PET-G  850 g.

The hub is from Anachronist's LockSpool.
