I bought a “barely used” RC boat for my grandchild's birthday and didn't notice that the right fin was broken until it was almost too late. A couple of hours of CAD work and test printing and we're ready to head to the birthday party with the boat in tip top shape with a few spares printed (since it appears as if they might break easily).
I didn't want to go through the ordeal of changing from my 0.6 nozzle to anything smaller, although I would highly recommend dropping down to at least 0.4 for this one.
I had to tweak my “initial layer horizontal expansion” (vs elephant's foot) and “hole horizontal expansion” in Cura to make the holes fit (tight fit).
If you happen to own this RC Boat, this will save you time in CAD, around $10 for the replacement ones but most importantly, you won't have to wait for 2 weeks to get it delivered from the other side of the world. ;)
You can also feel good about using a wee bit of electricity and 1g of filament for a pair vs the fuel spent for the components to be delivered to your house.
