GoPro Scuba Cylinder Mount
I've recently found an entry-level 3D online modelling software, Tinkercad and have been Tinkering ever since. I'm into scuba diving and I've long wanted to design a GoPro mount for the cylinder to give a 3rd person view of me while I'm swimming about enjoying life underwater. (Think a less-sexy Lara Croft!)
I wanted to run it past you guys to see what you think. I've attached 2 screenshots, because as you can see, the mount I've designed is collapsible, to save space in my GoPro bag.
I've done the maths (Pythag) so each side is perfectly lengthed to create a right-angled triangle, with the hypotaneuse (long edge) is facing down my body, towards my feet, so that the camera view won't be obstructed.
I've used a Pythag triple, so the arms measure 3", 4", 5". This was done for 2 reasons: a) It was easier to desine using these measurements and b) I don't want it sticking too far up from my cylinder so that it doesn't catch on wildlife/coral/divers.
As this is my first GoPro mount that I've designed, I've had to go on deimensions I've found online for the actual hinges. I've settled on approx 3mm for each prong as well as the gap in between.
I have actually shaved off .25mm from the middle prong of the 3-pronged-hinge, and left the 2-pronged-hinge at 3mm for the gap and prongs.
I'm going to get the pieces 3D-printed by a local service I've found on 3DHubs.com, either in ABS plastic or in resin, though I'll probably go for ABS as it seems to be a bit more hard-wearing, even if it's not so detailed. In terms of mounting it to the tank, I will use 2 headstraps, with the over-the-top strap removed from each one and glue the plastic bits of each of them together, at the correct length of course. I would join them using a seperate piece of plastic and either a hot glue gun, superglue or even some sort of epoxy, whatever lasts longest in prolonged exposure to seawater.
I would probably place it nearer the top of the tank, near to where the strap of the BCD jacket goes round it.
Does anybody have any advice for me in terms of the design from a functional point of view as well as from whether they think it would actually get a good shot on the camera please?
I look forward to your feedback, good or bad!
