Local school had a Swordfish Sketch electric pencil sharpener (model 40050) not working properly.
I found the small gear pinion mounted on the motor shaft had a crack in it so it was slipping. I modelled this replacement using Fusion 360. The replacement is not identical to the original because I have extended it to improve the strength.
I used PLA but other materials may be more suitable. I don't think the loading is particularly great so I hope it will last!
