Variable Diameter Sample Spools (Double)

thingiverse

After noticing that the available spools here are woefully inadequate for their intended use and necessitate screws and nuts, I decided to create my own spool after purchasing a sample pack of 16 filaments with varying diameters and tearing out my hair in frustration. You can print just one body and three arms, but be warned: the teeth on the body have a tendency to get caught by the side of your spool hook. Features: Each arm boasts two filament "catches" designed to grip the filament securely and prevent it from unspooling or getting tangled mid-print or when storing it. The flexible arms are there for an easy way to load sample filaments onto the spool without having to remove the arms first. Note: Pictured is an older version, but the uploaded design has undergone a few changes to strengthen weak points and add some style.
