A plug/cap for D2 rear spring perch body. Normally, the top is left open, and there's nowhere for the water to drain. Consequently, water pools up, rusts the bolt, and next thing you know, your drilling stuff. This is an attempt to prevent that. I tested it in PLA over the course of a year, and there was no apparent water and the bolt was clean. Condensation within the space did not appear to be an issue in the hot/cold/humid mid-Atlantic climate.
Seal with silicone RTV when installing. The through hole on top lets you use a screwdriver if you ever need to remove it.
