Printed both the kettlebell and the dumbbell. The kettlebell was fine, even printed it at 50% so it was more keychain size. The dumbbell has a bad design. The handle part should extend into the weight area on both ends. Instead it simply connects to the ends of them. which resulted in it breaking apart very easily.
No worries. I fixed that file in fusion 360 already. Reprinted and still broke. Then figured it was the orientation it was printing. It cannot print straight up and down. It has to print laying down so the horizontal lines extend from the handle through the weight area. Much stronger.
