A bit ridiculous I know but I hated getting pepper everywhere on the counter when I put the grinder down. There is always some bits that drop out and you are always cleaning the pepper grinds. So I made this up to keep the counter clean. Works well with the Peugeot Pepper grinder. It has a full diameter of 8cm but the inside diameter is 6cm for the grinder to fit in. Plus it has a little cup on the inside to collect the pepper :) I have a lower profile version as well and will upload it as soon as I test it.
