Thermoform Mold: Yoyo Dome

The thermoform mold for the clear outer dome is shown below. Areas that may need alteration are the diameter of the central circular bevel and also the shape of the dome extrusion. The diameter may need to change based on any unexpected shrinkage in the ring or base mold, and the shape of the dome may change for purely aesthetic or functional reasons after experimentation. 

Key features on this part are the exterior cut in the side of the mold and drill holes in the top, which will all be used to line the mold up in the thermoform machine. Vent holes will also be added to the to ensure a close fit on the mold.
