Nice. I got you @nevin I can reprint those for you, only pay for shipping.
Just wait to use it for like 2 days fully assembled, touching another regular mouse is gonna be like "Whats this stupid design"
Plastics on 3d prints will fatigue, if you bolt it/mechanically stress it, will fatigue even faster, is sub-mm layered heated plastic on top of other layers, thats why 3d print are for prototyping not for production, even more exotic carbon fiber infused plastics, just not as good as injection molding/resin.
I have a tendency to make things extra beefy for that reason alone, to avoid re-printing that part too soon. I can get a resin printer but its stinky and I dont want to store resin containers in my room.
How to clean sticky bearings, remove the seals and clean the lube with a paper towel, with a toothpick, remove everything you can
If "hops" on certain location could be that the crown touches the metal seal on the inside, removing those with a sewing needle could be all it takes. If doesnt, after cleaning the lube, submerge it in acetone or paint thinner of some sort and holding it with pliers and spin it, will dislodge whatever is trapped in there. I found myself blowing compressed air on it, its lots of fun jsut becareful dont spray nasty chemicals on workplace doing that
I re-lubed mine with bicycle chain oil, is not gonna be any high-load high-speed there, you could pass lubing it alltogether, smoother movement
Upload some pictures so I can see where the cracks are, I can modify the model to make it thicker.
