Log Loader Replacement Parts for Tyco Trucking US1

thingiverse

These are replacement parts for the Tyco Trucking US-1 Log Loader. This set includes the plastic armatures beneath the surface as well as the tractor that goes above. To build a replacement tractor, in addition to the plastic pieces, you will need 24mm long steel shaft that is 1.5mm in diameter. (Servo pushrods can be a good place to get 1.5mm diameter steel rods). This goes between the rear "wheels" and it serves as the mounting point for the tractor to the underlying armature. It also serves as a bearing for the connection to the tractor's scoop. When using an FDM printer, I would recommend printing these parts as shown above, using supports where needed. This will ensure the parts have enough strength in the right places.
