Brian Jepson is editing the Lego book Wayne & Layne and I are working on (it’s called Make: Lego and Arduino Projects) and he was faced with having to buy a ton of parts in order to test our models. Instead he decided to use his 3D printer to make his own!

Inspired by BitBeam‘s cool lasercut beams Brian created a version to be 3D printed. All you have to do is specify the number of holes, render it to an STL in OpenSCAD, and print! He calls them MyBeam.
