Some hints: - The complete model, measuring approximately 10 cm in height, was assembled and glued together using a soldering iron at 200 degrees (PLA). - A 24.5 mm diameter, 12.5 mm thick, 3-6 V solar motor with a 2 mm diameter and 10 mm length axle serves as the motor. This is similar to the RF-300CA or comparable models. - The gears must be precisely aligned in a right angle to their axles to prevent wobbling. - Archimedes screw bearings require widening using a drill or file, allowing for some slip. Vaseline should be used for lubrication. - There is also an electronic component that collects energy in a goldcap and drives the motor when sufficient energy is harvested. Three versions of the track are available: - A single piece (track_prop) - Split, low ground (track_split_gnd_low) - Split, props parallel to ground (track_split_gnd_prop)
