Williams Drop Target Guide P/N 03-7479 or 3B-7479 - *MODIFIED* Created by Outpost Kodelia (https://www.thingiverse.com/OutpostKodelia) License: Creative Commons - Attribution This is a modified version of the original Williams drop target guides, designed to outperform the original design. It gives the target more room to move while increasing electrical contact with the PCB, resulting in faster falling targets and more consistent scoring. Key improvements include: * Oval columns add strength to resist screw damage * PCB mounting is sloped and more supportive, ensuring easy drop of targets by relieving friction between horseshoes and the pcb as it tilts back and starts to fall * Main platform is thicker and stronger Version 1.1 includes a small spacing adjustment to match the ramp machine screw tower with metal frame holes better. Version 1.0 features more accurate measurements, tightened up PCB screw hole diameters, and fixes crookedness in pcb layout. Version 0.2 is based on SCAD recreation/remix by PL1 (https://www.thingiverse.com/PL1), with changes including a steeper ramp, added circular bases around hole entrances, increased height of the raised crosspiece at the bottom, reduced PCB screw hole sizes, and raised center wall. Version 0.1 is the first draft based on loose measurements, built without SCAD. Print recommendations: * Supports: Yes, including bridge supports * Optionally print on its side if you encounter problems producing the main platform successfully This part is used in Williams System 3-6 tables. Drop target assemblies that use the 03-7479 guide include: D-7931-#s - # = number of targets (between 1 and 5) D-8362 - 5 targets D-8442 - 3 targets D-9355 - 3 targets Screw sizes: * #6-32 x 3/4" machine screw - Mounts the guide to the frame * #6 sheet metal screw - Also mounts the guide to the frame (not in all games) * #4 sheet metal screw - Mounts the PCB to the guide
