WPC Drop Target

thingiverse

Bally/Williams WPC Drop Target, Used in Many Pinball Machines This design combines both flush and standard versions. A slight modification has been made to the original part: The spring is now inserted into an angled slit for easier printing, and all grooves have been widened slightly for better part tolerances. Note: Depending on the machine, the flap at the bottom may be used to trigger opto contacts. For this to work, the material used must block infrared light. A simple solution is to paint it with a black CD marker (check using your phone's camera and a remote to ensure it works). Print the drop target lying on its side, with the flap just above the build plate, using full interior and exterior support. It's best to print slightly hotter than usual to achieve proper layer bonding, as these targets can withstand significant punishment. PLA has been tested, but ABS or PETG would be a better choice.
