I couldn't find any 3D models of this 1970s classic, so I measured my “new” trailer and modeled it for printing.

Just as the classic camping Boler trailer is made, this comes in two shells, top and bottom, along with a frame and wheels.

I've also made a solid whole piece, which is slotted to fit the thicker frame. This is a more durable option - for me it will be my keychain!

Print the hollow top at the weird angle shown to minimize supports.

The frame prints best upside down to eliminate supports.
