Summary

Replacement charge port cap for Evolve GTR eskate, and possibly others.

Print in flex/TPE/TPU, something with some flex and GOOD layer adhesion. You don't want to tear it along the Z when you pull it off, and leave a chunk stuck in your charge port.

If that does happen, recommend bending a small 'hook' into a paperclip or metal wire, and stick it down the polarity enforcer space on the flat side, and try to pull it up from there.
