3D Printing a Body Repair - (Trolley07)

Welcome back to the trolley rebuild project! In this episode, I focus on repairing the body of a mid-70s AMH trolley. Using Fusion 360 and my 3D printer, I designed a replacement part to fill in a broken section of the shell and bring the model back into shape. Along the way, I share tips for prepping, gluing, and test-fitting parts before moving on to primer and paint.

In this video, I’m jumping back into the trolley rebuild project after taking a little break. The focus today is on body modifications for a mid-70s AMH trolley. I walk through repairing a broken section of the body shell and show how I designed and 3D printed a simple replacement part in Fusion 360 to clean up the appearance.

Along the way, I talk through the repair process—separating the body components, fitting the 3D-printed insert, and gluing it into place with CA glue (with the help of trusty tweezers). I also share some thoughts about prep work for primer and paint, as well as what’s coming next: adding the cowcatcher (or “people catcher”) to the front.

There’s even a guest appearance from one of my cats, because what’s a workshop without a little cat supervision?
