The internal mechanism of the wagon is supported by custom support with a PETG interface layer. If you are unable to provide petg, it will print fine, but it will lose some functionality

Assembly is relatively straightforward:

1. The carriages come in two halves that can be snapped together with a dovetail. 
4. The assembled carriage can be screwed onto the main body with the provided printed screws. Hand tightening is enough, but a flathead screwdriver can also be used.

5.  

6. The connector hook and rings can be press-fitted in (or glued if the tolerances do not allow the former). The same is true for the magnet if it is chosen over the hook.
