Go Pro Session Dud

I needed a weighted dud of a GoPro Session to make training flights with right weight and not to risk precious sessions.
Put something heavy inside to account for weight, e.g. steel washers, or... coins!

For extra strength (and weight) I injected some hot glue inside and added a couple of turns of electric tape. Hot glue gun penetrates PLA walls with ease.

UPD: Added ver 2 with enlarged inside hole for more convenient weight correction.
