SainSmart CNC 3018 ProVER Parametric Spoilboard (and others) -- Source Included

thingiverse

This is a CNC spoilboard I coded after looking at a few designs around the web. I wrote it for my SainSmart CNC 3018 ProVER with the Y extension (3040). If you have this machine, this may work for you, but check that the measurements are not out of bounds for your machine. Examine the source code. Most values are variables that can be modified to suit your setup. I used MDF from Home Depot, a big box hardware chain in the USA. I got the boards cut pretty close to size in the store, taped two together with blue painter's tape, clamped them down and let the machine do the work.
