YouTuber ProfessorBoots recently published a comprehensive set of 3D print files for a remote-controlled mini excavator. The STL files for free download on the Printables platform contain all the necessary components to build the functional model yourself.
According to ProfessorBoots, the set is also suitable for beginners. Thanks to the modular design, the individual components such as the boom arm, bucket and chassis are easy to print and then assemble.
The YouTuber recommends compact RC servo motors as the drive. They can be controlled via a special circuit board with a Bluetooth connection to a smartphone or tablet. Alternatively, a commercially available RC remote control can be used.
The building instructions are provided in the form of a detailed video tutorial on YouTube and on the official website. According to ProfessorBoots, the self-assembly takes around 35 hours of printing time. However, experienced makers could also complete the model within a weekend. Alternatively, ProfessorBoots also offers a complete kit with all electrical parts and the 3D-printed parts in its store.
