Compact Spice Grinder / Universal Mill

This mechanical grinder features a functional design and a robust gear ratio. It is perfect for anyone looking for a tactile and reliable solution for the kitchen or workshop. The ergonomic crank handle and precisely interlocking gears allow for effortless processing of your materials.

Printing Recommendations & Details

• Material: I highly recommend printing all components in PETG. PETG provides the necessary toughness for the mechanical stress on the gears and offers better temperature resistance and durability for daily use.
• Infill: At least 20-25% (Gyroid recommended) for extra stability of the crankshaft.
• Wall Loops: 3-4 wall loops ensure that the gear teeth remain strong and durable.

Assembly

The model is designed with tight tolerances for a precise fit. If the gears feel a bit stiff at first, a drop of food-safe silicone grease or simply "breaking them in" by turning the handle several times will help smooth out the movement.

Happy printing!
