Rugged hard case for iPhone8. For printing with hard plastic.
So, not crazy rugged, but there's two main features that make this more robust than a typical store bought case the first is the screen is inset into the case deeper than typical. There is about 1mm of plastic raised above the screen. As in, if your phone belly flops on its face there is ample plastic keeping the ground away from the screen. (The inspiration for this project is I keep braking my phone screens!!).
The other feature is the thickness of material around the perimeter is pretty thick 3mm as in if you drop your phone on the corner there is 3mm of malleable plastic to absorb the hit.
I went through 5 print iterations adjusting the fit and phone pop in details it's pretty dialed but FYI the fit is pretty critical especially regarding the buttons so make sure you have your printer dialed in and throw your best settings at it.
If you print this, FYI, the fit is pretty tight popping the phone in and out. (this is because the case is pretty stiff and the fit is secure) Drop the mute switch on the left in first, then push the phone to the top of the case, and then the bottom of the phone pop's in pretty easy. Word of warning it will squeeze both left and right buttons when installing the phone which activates the "sos" protocol. Just 'x-out' when that pop's up on the screen to avoid accidentally calling the police or something. Then when removing the phone, pop the bottom out first then slide the phone downward out of the case once the bottom is free.
I printed this with PLA. Works great.
Also I did a bit of filing and sanding to smooth the rough edges and printing artifacts.
The buttons are separate pieces. They are "loose" buttons. You need 3 of them, it's the same button in all 3 locations. Do some detail filing if necessary to make sure the buttons move freely in the button cavities.
The spacing and fit of the buttons is critical. I recommend using super dense supports, and generally speaking throw your best print settings at this to get a good result.
Print the exterior shell super slow. I recommend 25 mm/s. This is because the little detents around the perimeter of the case are pretty jerky so you need to go super slow be be accurate and get a clean print.
