About this 3D model

This is a Mecanum wheel http://en.wikipedia.org/wiki/Mecanum_wheel I saw that somebody else had a printable one, but it was not shared. So I made this. You will have to use glue, or acetone, or something to accach the pieces together. This is designed to use 3mm filament as axles for the wheels. I also uploaded the blender file, in case anyone wants to change stuff.
