Variable Cold Shoe Adapter

This is a variable cold shoe adapter for own plates, you want to create or just don't want to buy. I will create different plates day by day for my needs. You can add additional plates, if you like to. You need: 2x ruthex M3 insets to put them in the holes. To tighten the plates, you need normal m3 bolts. I used M3x8 for my double plate adapter
