Salt N Pepper Grinder

Ok, so I increased the size in 123D Design by a factor of 20. The original was pretty flimsy and broke as I tried to put it together. This version uses a 4mm nut with a 4x20mm machine screw to hold the handle to the grinder. The nut slides into the male grinder and the screw goes through the handle.

The improved handle also has strengthened female slot to accept the male grinder part so it doesn't snap off and features a round inner body to keep the shaker handle from slipping around all over
