I just bought my Yuneec Typhoon H with some spare batteries and needed something to protect the connections when traveling with it. This just slides on and stays there so nothing can give you a short circuit!
I printed it in 0,15 layers since that's my basic setting but anything should work, same with infill. Use something that you feel ok with!
Print it with the flat side with text down towards the bed and you won't need any supports.
