About this 3D model

I have played with lego technic parts for a while, and wondered if I could 3D print my own lego technic parts. This is a 3x1 liftarm for use as opposed to part #32523. Note: This is hard part to print with a standard 0.4 mm nozzle, because some walls are thin. I would recommend a 0.3mm or 0.2mm nozzle. This is an entry to the #FIXMYTOY MyMiniFactory design challenge.
