A bi-axle gooseneck trailer with dually tires, I printed the trailer and wheels with rafts, but only supports on the trailer. I used a .2mm nozzle, a layer height of .14mm. The axles, as on all of my Hot Wheels models, are straightened paperclips.
The author remixed this model.
I simply designed dually wheels for it, and I modified the hitch to make sure it would fit on my truck. This is the original designer, and he has some fantastic models: https://makerworld.com/en/@shaysidd
