This is a recreation of the plug which holds the odometer and blinker/high beam plastic lenses on an early 1984-1989 C4 Corvette gauge cluster. I printed it in White PETG as an example to show in the attached picture. This could very likely be used in other GM vehicles from the same era for similar applications. These plugs are normally sold for $5+ online individually! This file uses less than 1 gram of filament at 100% infill and takes less than 15mins to print. I took the measurements from an existing plug and used TinkerCad to replicate the shape the best I could. The fitment is very close to OEM. I recommend using PETG, ASA, or other resilient material considering it is in the interior of a vehicle, but PLA may be fine considering sunlight should not reach it.
