A larger herb grinder based on freightFright's design. Thank you for providing STEP files!
This version is quite a bit larger in size, and has a container underneath to collect ground material.
Would recommend printing in ABS or ASA and then smooth it with acetone. This might minimize amount of microplastics that fall off. Do not use this for anything you intend to ingest or inhale. I made this to grind herbs for essential oils.
The author remixed this model.
