O-ring for Battery Puck

O-ring for Battery Puck: https://makerworld.com/zh/models/674286-battery-puck?from=search#profileId-602307Printed with 95A TPU, softer material will be more ideal.Water-proofness is untested but the seal is already strong enough to make the cap kinda hard to remove. This should make the pod at least weather-proof.
