Williams Funhouse and Road Show eyeball crank (Beta)

thingiverse

UPDATE: Version 1.2 - The main pivot sleeve has been enlarged by 0.1mm, and the tail section has been adjusted to fit a missing part in my game. The use of support material is crucial, as several parts are pure cantilever structures. With Prusa-Slicer, I succeeded by enabling "Generate Support material", using an overhang threshold of 0, and 1mm pattern spacing. The default settings generated support material that broke the part when removed. I also advise printing in PETG or ABS for added strength. I'm experimenting with using through-hole grommets for the linkage holes. I will update as I determine the correct size grommet. This is a replacement part for Williams Funhouse and Road Show pinball games. It's the eyeball crank that's part of the mechanism making the eyeballs on Rudy (Funhouse), Red, and Ted (Road Show) move back and forth. The original part (Williams A-19258 or 03-8428) is both high-wear and hard to obtain. This project will be ongoing. As of now, the design aims to get as close to the original as possible while making it more suitable for standard printing. Further development will focus on optimizing for performance and durability as a 3D printed part.
