Designed to lift your filament out of the stand with great ease. Filament spool based off a Makerbot spool, yet designed to work with other spools. This filament holder was meant to be printed without supports. "FilamentPin" and "FilamentMid" should be printed vertically to get the best results at 0.20mm height. Infill and shells vary based on preference, but I would recommend 5-10% infill and 2 shells. The entire print should be about 100 grams of filament. Version 2 has been tested to work in ABS. Good luck printing and enjoy!
