If you are inspired to do the same - modelling time 15 minutes in Fusion 360 - cutting time 18 minutes. FUp Clamps in the back of the cupboard… . ---

I like those and I like the idea of using copper pipe over wood dowels or pvc. ---

I discovered at the bottom of my scrap bin. I’ll be doing some more out 1/2", 3/4" and 1" birch ply I have at the top of the scrap bin.
