I bought the amazing Mannkitchen Pepper Cannon for my dad a few years ago (the man has never seen a meal he thought already had enough black pepper)
Unfortunately both of my folks have issues with the use of their hands, and the relatively-small and sharp edges on the top of the mill make it uncomfortable for them to use.
3D printing to the rescue! This is the first of a couple designs for a more-comfortable and usable grip for the top of the pepper cannon.
Example photos were printed in Bambu Matte Charcoal on the P1S – the sizing is juuuuust right for me with my setup, but your mileage may vary.
