Extension Cord Spool for 53mm Spools

A friction fit cable holder for your extension cables. This reuses your empty filament spools and puts them to good use. Just drill a hole on the inside of the spool, and fit the female side of your spool through. 

I've included 10 and 15 mm inner diameter versions of this. Just print 2 and click them together. If you have a different diameter spool to recycle, just scale it to fit.
