Wiper-Linkage Drive Gear

Replacement gear for the single-arm windscreen-wiper mechanism. The creator documents the dismantled mechanism, press-fitting the gear after heating the splined shaft, and specifies nylon at 100% infill. Treat this as a mechanism repair: compare tooth count and shaft profile, preserve alignment and lubrication, and bench-test full travel, parking and stall behavior before wet-road use.
