My son got a Mastercraft Wakeboard RC boat, and wanted a trailer to tow it around with his RC Truck.
I couldn't find anything to suit, so used some of the design from https://www.thingiverse.com/thing:2842363, and modified most of it..

I have also included the towbar that i designed to fit on the RC truck. connecting the trailer to the truck is via a bolt.

I printed all on a Anet A8 clone, with 10% infil.

Everything is glued together, except the wheels are screwed on.
