Lego Mindstorms EV3 Beam Brick (based off red 11 hole)

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/f2RWiYZiEwq It should be accurate to .1 mm. UPDATE: I have uploaded hopefully the final version that has holes with BOTH internal diameters .4 mm larger to accommodate material deformation. My previous revision had only expanded the smaller of the two internal diameters, which does not account for the larger space meant to accommodate the flanges on the posts. I have kept the original version in case your printer has higher tolerances. By slicing, rotating, and remixing this brick, you should be able to create new beams to use in your custom robot builds.
