Below you have the link to download the 3D files. You will have the main base, 2 big hinges for the balance, the support for the servo motor with holes for M3 screws and the disc that will be connected to the servo motor. For this you will have different sizes. You will also have some small parts to transfer the force from the servo to the balance, and that's it. The rest is made with plywood parts. Print the 3D files with 2 perimeters, 20% infill, 0.4mm nozzle and 0.2mm layer height. You have different size wheels in order to have faster or slower movement. This will also affect the results.
