iPhone 6 bracket for car

My wife’s Honda Civic had a small pocket/cubby with a flip down door just below the stereo. On a recent road trip we found the door to be a good platform for an iPhone 6 running Waze, but it kept slipping off of the door. While a folded up napkin did an ok job of keeping it from slipping off, I thought “I can over engineer this!” so I did.

The idea was to make a 3D printed bracket that could be double-stick-taped to the door, allowing it to close as normal, but holding the phone when opened.

We both have Spigen bumper cases for our phones, so measurements were made for that. The design was completed using OnShape (this being my 2nd real thing modeled and 3D printed using the program).

Prototype 1 was much too big and clunky to allow the door to close, and the tolerances were a little tight for the phone even though it “fit.”

Prototype 2 was much smaller (and eliminated the end stops just to see if it would fit), but this still proved too big; the height of the base was too tall, as was the height of the back support.

Prototype 3 reduced the thickness of the walls and floor greatly, and added the end stops back in. The design was no longer symmetrical (like the first prototype) so a quick reflect was used in OnShape to make the second bracket.

The third design ended up working and fitting great. The door closes and the design is less clunky in general.
