150mm mitre box

What you'll need:

Pretty specific. This is a mitre box for cutting 150mm blanks for Antweight(UK) / Fairyweight(US) robots. You slide a 1 inch wide 1/8 inch thick piece of barstock (aluminum/titanium/steel) into the mitre box and cut it with a hacksaw. The holes in the back are dual purpose:

1) it saves filament
2) when you are left with a burr on the end of your stock you can push through the holes t
