These GoPro protective cases are designed to be printed using PLA and not TPU. I'm almost certain that they will not work well in TPU format at all. So if you go down that path don't complain that one cable tie doesn't work or you're getting jello in the footage.
We've run these cases since the Aliens first came out and today we haven't damaged a GoPro, having said that I'm sure someone will hit a light post at 100mph and they'll manage to explode a GoPro.
There are 3 main types of Mounts here. A 30 degree and 35 degree tilted mounts that will work with almost any Alien Style Quad using one Zip Tie to hold it down. We also have a mount with Zero tilt and it's designed for the Helix. You'll notice on this one there is an access section for the MicroSD and Charge Cable which you can break away if desired. On the Helix this is the mount we use and once you cable tie it down, you can't access the the rear to remove the GoPro so hence the hatch for MicroSD Access and Charging.
The fourth part is the main face plate which will house the Lumenier lens and also take the main impact in a crash.
You will need to purchase Lumenier Layer Lenses since this is what this design is based around.
For those of you who are going to ask I've finally enabled Thingiverse Tipping.
Anyway I hope you find these files useful
