Planetary Gear Autopilot Raymarine ST4000+

Replacement gear for a Raymarine ST4000+ autopilot, we all know they break easily if forced, and replacements are hard to find, so here you go.

We don't guarante they will last forever, but they do the job, if you want to try printing in other materials feel free to comment your experience, we thought that PETG would be best because it will break before damaging the outer shell.
