Theatre of Magic Pinball Trunk Opto Interrupter

thingiverse

The Bally Theatre of Magic pinball machine opto interrupter wheel that controls the magic trunk is prone to cracking, this is a replacement for that part. In 2 parts for ease of printing. The original set screw can be used, I suggest a trial fit of this in the 'hat' part before final assembly in case it splits then you won't have to reprint the whole thing. Then insert the 'hat' part into the underside of the 'wheel' and glue in place. You could probably drill through both parts and use some nuts and bolts to hold the two pieces together if you were so inclined. When installing ensure the set screw goes into the divot on the shaft so it's all lined up. You will probably need to remove the pins from the wiring connectors going to the trunk to get the new part on.
