thingiverse

UPDATED NOTES 5th November 2013 added two newer versions 1.3 and 1.3a for hero 3 added two newer versions 1.2 and 1.2a for hero 2 identical to previous version, but includes a gopro name plate on the fronts 4th November 2013 added two newer versions 1.2 and 1.2a for hero 3 added two newer versions 1.1 and 1.1a for hero 2 revised to have thinner walls- less material needed, the 1.2a / 101a experimental version are added with tabs to allow the use of an elastic band, to secure the cover in place better. (i had found that my cover would fall off too easily after the cap has been used a number of times or if the gopro was put into a bag or pocket, it just worked its was loose.) neither printed yet. 6th June 2013 I REVISED THE GoPro 3 cover, removing the side lips, as i found it a little tricky to open the GP case when the cover was on, this should open up the finger space a little more to make things easier, but still providing a lip on the top and bottom edges, to enable removal GoPro Hero 2 / GoPro Hero 3 lens cover for case ive seen ones similar on thingiverse, but i never have much success when using other peoples design for items that have fine tolerances, so i knocked my own up using my own measured off dimensions and it turned out to be a nice snug fit, the radius on the hero 3 are a little off but it doesnt effect the way it mounts to the camera case. i added a small recess on the cover top, so that there is less chance of the cover binding on to the lens face. this was supposed to be a tolerance test piece, prior to me adding to it, but it was such a good fit on the first attempt i thought id upload it so that others may benefit from it. i will amend the design fully when i need to replace my current lens covers Instructions i printed at 0.2 layer in PLA 215 degrees and an infil of 25% 0.8 wall thickness, 0.6 btm / top thickness, print speed 50mm/s
