A printable version of the wobble goal from FTC 2020-2021, Ultimate Goal, useful for rough sizing and simple testing of a gripper. It should be very close to the specifications, and when printed comes out very close to the correct weight, but weight could be increased by adding ballast inside the dome.
When printing, I print the dome upside down to keep the support internal. I used very limited support on the two parts of the stalk, and printed the middle piece horizontally for strength. It is not as strong as I'd like - for additional strength a piece of aluminium tubing could be run through the the stalk, but a hole would need to be inserted to make this possible.
I did design a 2-part dome for smaller print beds but the CR-6 SE arrived, and that is big enough to print the full dome in one piece. If needed I can upload the half-domes, but they are not fully tested.
STEP files are included in case you need to make modifications.
