Fully printable - no support - no glue - single color 3D printer

This is a semi truck toy with a dump truck trailer.

Assembly video (semi truck) https://youtu.be/TJCMTOk385A Assembly video (tank trailer) https://youtu.be/-EAHEBORbbY

The semi truck is more or less the same as the one with the tank trailer: https://www.cgtrader.com/3d-print-models/games-toys/toys/semi-truck-toy-fully-3d-printable-assembly-experience

For the dump trailer print as many middle modules as you want to get the tank length that you want. You will need however to print the longer dump_semi_connector_L.stl and more connectors and screws for this!

You can also make a short version with the pieces from this model (see 3rd to 5th pics).

The tolerance for pieces that need to fit tightly is 0.1mm, for pieces that need to allow movement (like screws and axles) 0.3mm or more.

Observations:

• all objects already have the intended print direction in the STL files!
• most of the parts were printed with PLA. only the tires and the mirrors were printed from TPU (flexible material)
• screws... there are also sleeping screws STLs included these are printed on the side which makes them a lot stronger the drawback is that these don't close the holes completely... So use as many sleeping screws as you can if the toy is going to be played with, and only normal/round ones otherwise
