100mm Mitre Box

thingiverse

What you'll need: -This print -Metal bar stock. 1 inch or 2.5cm wide, 1/8 inch or 3mm thick. -a Hacksaw Pretty specific. This is a mitre box for cutting 100mm 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 to make it easier to get your cut out. You probably want to print this fairly solid (i think i did 50%) as you're going to be using this with a hacksaw. You also want to make sure you get a really clean print on the first few layers and that you remember to remove that dangley bit a filament off your nozzle before you start printing because if you have a bit of filament trapped down there you won't be able to fully insert your stock. After you have your blank cut it's up to you to decide how you want to get your mounting holes in your blade. Personally I like to design my drill pattern in Inkscape, print it out on paper, tape one end down to one side of my blank squarely, spray Super77 on my blank and then squeegee the pattern down onto the blank and blast the holes out on a drill press. By the way if anyone is looking to get rid of an extra mill, CNC or otherwise... :)
