PRO-BRACKET
Why am I making this?

Touge (峠, tōge).
The Japanese term "Touge" translates directly to pass, of which mountain pass roads were raced on during the late 1980's. With a great handling car and a little bit of time - why not have some fun at our local roads?
Test: GoPro mounted to my head to record driver position and scenery ahead of vehicle.
Result: Lots of fun. Ran over a HUGE rock that killed my undertray.
Review: "Is it just me, or is does this footage look really slow? This looks boring."
Problem: Need to alter the angle to make my driving look more intense.
Solution: Relocate the Go-Pro to a lower position where the road speed is emphasized.
Pro-Bracket V1
Material: 3D-printed PETG
Description: Create 3D-Printed board with GO-Pro holder that fastens to 2 open fastening points dedicated to holding license plate.
Expected Failure Mode: Based off first principles, unlikely failure due to high FOS of materials but extended fastening regions will be of high stress.
Review and reiterate. How to improve?
Increase thickness or radius of material around bolt holes.
Shift Go-Pro position up and in between fastening points.
Offset from license plate instead of flush.
Pro-Bracket V1.1:
Material: 3D-printed PETG
Expected Failure Mode: TBD after test.
Description: More centralized load between fastening points. Beefed up fastening points, and reduced cover (it probably won't fall out). Harder to print need more supports
Additions: New press-fit lid attempt. Will inspect fitment after 3D print is made tangible.
Actual 3D-Printed Result:
Looks great! Mounting holes don't line up with the car. Should've added slots. Need redo.
I think I took the distance from edge to edge and I forgot to add the two half lengths of screws. Or maybe I just measured it wrong.
Reiterating now with slotted mounting points and more thick walls (GoPro loose and shaky, too much wobble). Also needs to be taller in design, too low on license plate.
Pro-Bracket V1.2:
Impression: This is awesome. I'm going to hit the mountain roads with this thing. Lets see what the driving footage looks like compared to the boring one at the top of this page!
