Maker Box Filament Spool

This is a very basic filament spool designed specifically for the Maker Box filament samples. I wanted something simple l that I could print quickly and that would fit back in the original bags. There's two versions available: The standard version has a 55mm diameter center (the same as Hatchbox). The minimal version removes this center to use even less filament. Both versions have a 110mm outer diameter, which is what most of my filament samples come already wound to. This allows the spool to be used in two ways: 1. Wind the filament onto the new spool. 2. Sandwich the filament sample between the two pieces. This is far easier, but you may have mixed results since the filament isn't as snug and there's no easy way to tell if the filament is tangled around itself, but I've had pretty good luck so far. I recommend keeping the twist ties on until it's assembled. You'll need a top and a bottom piece for each spool. They're designed for compression fit, but you might need a drop or two of super glue depending on how yours prints. Note: I've only tested this with the 1.75mm filament samples so far. If there's any way I can adjust this for 3mm please let me know.
