I use these connectors to wire out the battery of my scooter so I don't need to disassemble it if I want to charge it, but I felt like it is better if it has a cap for keeping the dirt and splashing water out.
It needs to be printed with TPU, because it is 0.2mm smaller than the connector, resulting in a nice tight fit with TPU.
I printed it in Azure TPU (85A)
