Boat engine pullcord spool
This is a replacement spool for the rope starter on a 1980's Johnson outboard motor (6-8 HP). The manufacturer has discontinued making the part and used ones are hard to find. I modeled the spool with the original dimensions and then created another copy to thicken up walls that, I feel, are too thin for a 3D printed part. I printed the part in a horizonal position so the layers were in the best orientation against shear stresses. I also used PETG filament as a minimum until I can print it in nylon. I fear PLA would be too brittle. So far so good! Hope this can help someone else.
