Rostock Hole cut and drill jig

I wanted to build an original Rostock but unfortunately, it was incredibly difficult to find plans for the top and bottom base. Even then, when I did find them, it would have been impossibly difficult to get accurate holes simply by measuring, drilling and cutting on a scrap piece of wood without a decent datum edge.

It was then that I designed this jig

It is also small enough to be printed on my CTC replicator clone
