Upgrade the stock pop bumper on your Stern Fallout pinball machine with this custom 3D printed cap featuring a Vault-Tec inspired radiation gear design. This translucent yellow replacement cap swaps out the factory clear dome with a bold gear-and-trefoil silhouette, so the pop bumper's under-light shines straight through the radiation symbol for a glowing wasteland effect during gameplay.

Designed as a direct drop-in replacement for the lower right pop bumper, this mod keeps your machine's lighting and mechanics fully intact while adding a striking visual upgrade that fits right into the game's Vault-Tec, Nuka-Cola, and post-apocalyptic aesthetic.
