ND Miata Shark Fin Delete Plug

I removed the shark fin antenna from my ND Miata MX-5 (2022) to install a custom GMRS radio antenna, but my new antenna was delayed in shipping. To avoid water from getting into the trunk, I designed this simple TPU plug that easily pops into from above and can be easily popped back out from underneath. The shark fin antenna on the Miata is only for XM radio and only causes a non-intrusive pop-up on the infotainment, that goes away.
