Instructions
There is only a single Sketchup file for the two STL files. This is because you need to print a mirror image of the sketchup file to allow for the tabs on the left front and left back of the TOM. So you need to print four of these supports, with at least one of each type.
Once printed, just slide them under the corners of your Thing-O-Matic and enjoy the greater sense of stability:)
