Filament Spool Tops

First World Problem #473: Empty Filament Spools Turns your empty spools into giant spinning tops! These easy-to-print inserts are designed for the 53.5mm dia holes in eSun/Inland spools, but you can easily re-scale them anywhere from 75% to 125% to fit your particular spool. I've posted three different style tops online. The spiral design gives an interesting visual effect when it spins, but it provides the least grip when you go to spin it up.
