I had a request to remix my iPhone bumper case into a full case with a back so here is my dotty version. I designed it this way so that the case back protects the back while all the cutout dots allows it to thermo-regulate better than a standard case. The back also has openings for your camera and flash and protrudes just far enough to protect the camera from scrapes.
You shouldn't need to clean up the print as it comes off very clean. The attached video is from the bumper case I made but it's the same except for the added back.
The other benefit of this case is that it fits both the portrait and landscape stands I made for that bumper case;-

Make sure you read the "post printing" section before putting it on your phone.

Print this in the orientation supplied.
I now mainly use Simplyfy3D to slice for three main reasons;-
- the supports come away beautifully and
- for items that rely on tight tolerances (like this case!) it prints the most accurate that I've used and
- You can specify different print settings in a print so for sections with detail you can reduce layer height and for uniform sections you can increase it and get great looking prints done fast!
I suggest printing with 4 perimeters and 25% infill as there's only a handful of grams of plastic in this so don't skimp.
I suggest printing this in an improved PLA (see below) or other filament that's strong and tough.
Beware: Not all PLA's are made equal.
Most of my prototypes and a good proportion of final prints are with an 'improved' PLA from Esun called PLA Plus (sometimes called pro) and it's tough and definitely not brittle and it's really cheap too. Some other moderately priced improved PLA's I've used are Filamentum, Prusa Brand & Colorfabb Economy PLA.
I haven't tried Hatchbox, Matterhackers, Taulman InPLA and Filaform Pro PLA but I hear some good things about them.
I also use a few better quality name brand PLA's for special one off jobs like phone cases and these are quite a bit better than the Esun though up to triple the price... though bare in mind this print in the pricey filament would still only cost a couple of bucks.
For the best looking prints with a fair bit better toughness than the Esun I use either Polymaker PolyMax PLA or ColorFabb PLA PHA. If excellent toughness and strength is a priority then the Polymaker PC Max polycarbonate is the one I'll always reach for and the finish is still good too.
It has a nice gentle chamfer so there shouldn't be any need to clean up the print if you print it as is on its back. Just remember that although your PLA might be tough it's normally not as flexible as the rubber cases you might be used to... so take a bit more care getting it on.
It's designed to fit in bottom first, sliding in and then gently easing the top in until it snaps into place. Take a look at the end of the bumper video (at 2:40) below to see how it's done.
This is from my bumper case but if you look close to the end (@ 2:40) you'll see me demonstrate how to put the case on your phone
