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 8 studs long axle that can be 3D printed that can be used in place of part #3707 Note: This is hard part to print, so it may be tight at first. I recommend printing at 0.1mm layer height to get the best fit. This is an entry to the #FIXMYTOY MyMiniFactory design challenge.
