You can CaReFuLlY shave down the corners of the 7135s. Ain’t much stuff in there, only epoxy.
Always want the most pressure against the rings that go around the periphery of the driver, to make solid (ground) contact with the pill/case/etc.
Ideally it would be soldered right to the pill (gotta use the hot end for that, though, not the handle) for best electrical contact, but ain’t too moddable after that.
