bench dog rack

I bought myself a used B&D workmate, But it didn't come with any bench dogs. So I bought a set of 4 from aliexpress (before I had a 3d printer), and then I didn't have any place to put them. Black and Decker really should have put a rack some where. SO when I got a 3d printer, I found a rack on maker world. https://makerworld.com/en/models/1057524-workbench-bench-dog-rack?from=search#profileId-1045228 But is was 6 positions. So I redesigned it to hold my four.
