This is for standard size popsicle sticks which I measured to be 113mm x 9.5mm x 2mm.
Print a single hub to test the fit of your popsicle sticks and adjust the XY Size Compensation until the stick is snug, but not too difficult to fully insert. If the sticks are too tight, there is a danger of breaking sticks and injuring yourself. Be careful!
For the full sphere, you will need 12 5-hubs and 30 6-hubs. For a half dome, you will need 6 5hubs, 10 6hubs, and 5 each 6hub-domebase-left and 6hub-domebase-right.
The hubs have markings on the bottom to help with assembly. the A sockets on the 5hub each connect to an A' socket on the 6hub. The B sockets on the 6hubs each connect to a B socket on another 6hub. As long as you connect in this way, the sphere will form. Assembly gets trickier the closer the model get to complete. At the end, you will have to gradually work several sticks at once until they're all tight.
edit: added a flat version with no lettering on the bottom for easier printing. On the 6-hubs, the longer legs connect to other 6-hubs and the shorter legs connect to 5-hubs.
