The idea with Basic Trailer Project is that you can combine standard parts to make your own trailer design. It is built with screws and nuts so you can change, upgrade, repair or take it apart and build something else.

Twist and turn the objects so that the print fits you and your printer.

Now we need something to hold containers on to the trailer. It's quite simple but it works, at least with my homemade containers (coming soon). Should work with Tamiya but as I don't have any I can not try.

Assembling as shown in pictures and video, could need some sanding.

The upper frame for this trailer is 425mm long, to fit 20' container.
