Mini Filament Spool

prusaprinters

No description needed. A small spool that fits 50g filament samples. Inner diameter is 50mm, should fit most spool holders “spool light” is very slim, uses about 10g material. Outer diameter is 100mm, 13,5mm height. I use this mostly for mail delivery of samples. Ist still fits 50g samples and is small enough to fit into a delivery envelope with max 2cm thickness, which is at least a limit in germany for cheap delivery. In a A4 envelope 3 spools fix easily, keeping 2cm thickness and still below 200g. “spool thick” is a reinforced version, especially thicker sides, uses about 28g material. Outer diameter is 110mm, but ~17mm height. As you can see on the title photo it fits a ~50g sample easy.  Also see my other tools, e.g the filament wind helper to use with this spool:https://www.printables.com/de/social/499583-bratensosse/collections/492704
