For over a year now, I've been signed up for Proto-Pasta's Endless Pastabilities which sends three 100g spools of Filaments every couple of months. I absolutely LOVE Proto-Pasta and look forward to getting these unique filament colors like a kid at Christmas!
Over the past year, I've been fine-tuning a spool for these 100g coils, and I finally have one I am proud to share. This spool is two separate pieces that thread together. There are eight holes around the base to feed through the 'start' of the filament and keep it locked in. Also, there are 16 holes around the perimeter of the lid to hold the 'end' of the filament when it isn't being used.
The author marked this model as their own original creation.
