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 :-) Please leave a "LIKE" and post a picture if you downloaded and printed it. Print settings (Simplify3D/Robo3D) Black 1.75 PETG Filament from WINBO 0.4mm nozzle, print speed 50mm/sec. Top Solid and Bottom Layers: 5 Outline Perimeters: 2 100% Infill NO Support or Raft needed - it prints very nicely E3D V6 Temperature: 250 degree celsius Glas Bed with hairspray at 90 degree celcius As you can see, my GoPro floats now very well and is "Safe At Sea" acccording to SOLAS, as designed and "Made in Germany" ;-) https://www.youtube.com/watch?v=yBhE2W_Q9nA
