Printable tractor trailer that fits Bruder tractors and a bunch of no name brands.

It is fully printable, you do not need any screws just a little super glue for the back side mounts.

Everything will fit perfectly if your printer is calibrated.

Printer settings :

I recommend atleast 4 walls, 20% Gyroid infill or similiar. I printed the trailer base in ABS, sides in PLA.The trailer base needs support for the wheel axis.

How many of each part you need is in the name of the STLs uploaded.

Assembly instructions :

• The front side mounts are press fit into the base and should be stiff enough without glue, you can however use it.
• the back side mounts need to be glued on with super glue as i will add some tail lights and some details in the future, when there is time.
• Side mounts slide just in
• The wheel caps are press fit to hold the wheels. You can glue them on if you prefer.

The wheels are wide, small and very close to the base. I made it so that when my son pushes too hard down the base leans to the wheels so the wheel axis does not break.

I printed the trailer as big as my printer allows it, hence the size, however, i have added the .stp file so you can upsize it however you like. Just print an adapter for the hook up hole on the trailer base so you can still hook it up when upsized.
