Big 1/16 Trailer for RC Cars like WPL C24 C54 C64 or MN82 MN Model D90 D99

This is an (almost) completely printed trailer for 1/16 RC Cars like WPL or MN Models.
The trailer can either transport another car or, with the additional box, many other things.
You will also need a few M3 screws to mount the trailer and longer M5 screws as axles for the wheels.
The wheels can either run directly on the axles or be used with ball bearings.

I printed all parts on an Ender 3, so the sizes are right for that.
I glued the box with superglue.
On larger printers the box can also be printed in one piece.
There is an STL file of the complete trailer so you can see the structure.

I printed the trailer out of PLA, but PETG would probably work too. The tires should be printed out of TPU.
