7.5 mini train bogie (trucks) (train wheels)

This is an edited and scaled-up version of this 1/32 bogie design.

For best durability, it is recommended to print this in PETG, ABS, or carbon fiber filament if you need it to support weight on the tracks.

This is an early model and will be updated eventually to include cargo and passenger cars.

We're testing the first model with these bearings: PrecisionPro 625/618-4 Bearing. However, they don’t seem to spin well. You may want to use metal bearings instead. We’ll be updating the bearing model soon with improved 3D-printed bearings that work better.
