GoPro Floaty / GoPro Pole - absolutely watertight by printing with PETG - NO Support needed!!!

As I didn´t like most of the existing GoPro poles, I designed one by myself via Tinkercad last week. The shell thickness is 3mm - so the pole is very stable, but not too heavy.
I hope you like it? Let me know, if you require any modification or change - I will try my best accordingly :-)
