About this 3D model
If you already printed the Hex Spools and didnt see the Remix with Labels ( https://makerworld.com/de/models/36802#profileId-35070 ) , this is a clip on Label for the Spools. Also you can now label both sides if you want ;-) A small Arrow on the Backside indicates the orientation( has to point to the center of the spool). I printed in PLA and it works great.
