Overview

This is a complete set of functional parts for the 1.2m Harbour Tugboat Model available at MakerWorld from this link: https://makerworld.com/en/models/1843800-1-2m-rc-harbour-tugboat-harbour?from=search#profileId-1995660

These parts contain all of the 3D-printed parts you need to make the 1.2m Harbour Tugboat Model fully functional. You will also need to buy electronics and other parts, and a complete part list is available as part of the downloads. These files are available either as separate .stl files or as a complete .3mf file.

Motor Mounts, Servo Mounts, Rudder Mounts, and Propellers The original model had no motor mounts, servo mounts, servo arms/horns, rudder pins, or propellers. So, I've created all of those things for you. This download includes a complete set of motor mounts, servo mounts, rudder mounts, and scale-appropriate propellers (100mm diameter with 1.20 pitch), which were all missing from the original model.

These are the exact parts that I used to make this boat operational.The photos for this download show how they are mounted in the boat.

Assembly Instructions & Parts List I've put together basic assembly instructions for the functional parts to explain how they're installed and a complete parts list for parts that you need to buy to make the boat functional. Both are available as a downloadable PDF.

The parts list for parts that you need to buy to make the boat functional includes radios, motors, servos, electronic speed controllers, and drive shafts, along with a cost estimate for the purchased parts. This is the exact parts list I used, and it works fine.

History As far as I can estimate, this is a 1:22 scale model of a 1960s-era tug boat. I did a number of estimates, but the closest one was made by printing a 6-ft tall (183m) person at several scales until he "looked right" looking out of the windows in the helm. The prototypes were 78 feet long.
