I wanted to make an adjustable Filament Spool, especially for Faberdashery Filament und without the need to add an extra mount on my printer. The Hole in the Center is the same size as most Filament spools you can buy, and you can use it with loose filament reels from 140 to 300mm in diameter. The 2 Center parts should be fairly easy to seperate. The adapters can be used for smaller spool holders to reduce the hole to 30mm. The second pin is for fixing the loose end of the filamentPrint all the Parts and assembly the arms. Print Pins with high infill and 4-5 perimeters! Be careful when removing pins from arms! Put Filament on one half of the spool adjust the pins for diameter and put on the other half.
