ABS or UHMW discs with holes for sticks around the outside edge.  Since the holes are drilled using an index head on a drill press with a mill table, it is possible to drill holes at any number of degrees, in increments of one degree. That means, yes we can do 22 degrees or 23 degrees; but not 22.5 degrees.  If your design requires the framework to be glued into the tinkertoy fitting, you must order ABS.  The UHMW is lighter and cheaper, but it cannot be glued.

Because of the number of variations, we require you to telephone your order into us (1-610-395-3560). When you order, you must specify what size spar you will use and the number of holes around the fitting.   Remember, UHMW cannot be glued.
