Percy’s New Frame Is Ready to Print

Percy’s new gearbox required extensive modifications to the frame. Fortunately, these were all 3D printed parts, and so, the changes were a simple matter of drawing. I decided to replace the rather nondescript motor cover with something a little more representative of the real engine’s frame. The ghost of Percy’s original frame is still present, however, and so it is impossible to get an accurate model without a lot of work, and that is something I’m trying to avoid for this experiment.

The original parts of the frame are shown in grey. All other parts required modification to allow for the new gearbox, which drives the rear axle instead of the front one. The rear coupler box was also modified to allow for a Sargent coupler experiment.
