I 3d-ified the design by stickoutrock and made it so the crosslinks snap into place.
Print two each of the STL files, clean, and snap together! Make sure the gears are aligned correctly; if things aren't sitting right, rotate one of the gears 180 degrees and try that way (they are not rotationally symmetric!)
