The Hario Mini Mill makes an ideal pepper grinder, blowing many dedicated pepper grinders out of the water, as it outputs a lot of pepper for each turn of the handle. The adjustable grind size is also nice to have, of course.

This design gives you a shorter, open-ended grinds cup which means pepper can easily be ground onto a meal - like a normal pepper grinder! The chunky knob is also easy to use as not much torque is required to grind peppercorns (as opposed to coffee. It also means that the grinder has no tendency to fall over anymore.

Printed in PETG at 0.24mm layer height for the cup and 0.28mm for the knob.

Printed on Ender 3 S1 Pro with speed profile in PrusaSlicer.
