A simple friction-fit hand grip that adds a thumb stop like on the M47 Simplicity to the M47 Phoenix. This part doesn't need to be food-safe since the grip goes below the beans funnel and should never make contact with the beans.
Since this is a slight interference fit, you might need to sand or add a bit of material/adhesive/tape to get the perfect fit for your specific printer/settings/filament. I'd recommend printing the model upside down from how it is oriented when on the grinder with supports as the sloped surface is hidden and not a mating surface.
Note: modifying your grinder could void your warranty. I take no responsibility for damage or voiding of your warranty if you use this mod on your grinder.
