One day I was browsing through 123D and Thingiverse when I noticed that no one had ever made a pinhole camera for the iPhone. Here we are in a world where 3D printing is a thing that exists and people are still taping tiny-holed cardboard squares over their iPhone cameras to achieve that coveted grainy look. Now you can save yourself the public humiliation of running around with cardboard on your iPhone and just 3D print a sleek plastic camera attachment instead.
Step 1: Copy an existing iPhone case on Tinkercad
Netflix exists so you really don't have the time/patience to make your own case from scratch, am I right? I used this one. Simply click the drop down TINKER menu and select "duplicate and tinker" to work on the case on your own.
I promise the dimensions are correct and perfect-fitting, so you don't have to compulsively measure like I did.
Step 2: Chop it allllll off (or 80% of it)
You don't want to have to wiggle your entire phone in and out of a case to take a pinhole photo.
For the sake of ease, let's turn this phone case into a phone attachment. Cut about 80% of the phone case (leaving just a little room under the camera) by covering the section to be chopped off with a cube. Then, make that cube into a hole by selecting it and shifting from "color" to "hole." Then, group the hole and the case to chop off the bottom components.
