BL FILAMENT SAMPLBE BOX

This BL filament sample box was designed to fit the BL filament sample string, but it can also hold the BL filament samples and additional self printed samples (up to 95 samples of the same size) while attached to a 2mm ball chain. An STL file of the BL size compatible FILAMENT SAMPLE is also included. The top slides on to the bottom with some resistance, but will slightly loosen with use.
