Dr Who Time Expander Opto Cover

The Dr Who pinball machine uses a #03-8655 Bally/Williams plastic base. The opto sensors are susceptible to light contamination from both outside the mechanism and inside. This resolves it once and for all.

Does replace the paper light shield.

Does not replace 03-8655, but instead fits inside it with a friction fit. Completely disassemble mechanism before installing.

Recommended: black filament, 98% infill, ABS material
