Notes:

You need at least 155x95mm build volume for this model. Preferably around 155x250 to get it all in one.

Post-Printing

Put part A on the side down and insert the Part B in center of each three-hole-group. Part C goes on the sides. Lastly flip everything over and align the assembled parts into the last Part A and push them together.

Some filing may be required!

How I Designed This

This was designed using Autodesk Fusion 360 and using the tyres as measurements from the http://www.thingiverse.com/thing:1193309 model
