I drive a 2018 Tesla Model 3 with the first-generation center console that did not have wireless phone charging built into it. So I purchased the popular Jeda brand phone charging pad. It worked great with my iPhone 12 Pro (medium-sized phone) but my iPhone 13 mini will not charge when placed on the pad. I can put a pen or pencil along the bottom to bring the phone upwards a bit, but it still moves side to side as I drive and stops charging when that happens. As with all problems in life, a 3D printed solution exists!

The photos show what this item does better than my description, so take a look. Note that I made this in red/orange simply for better contrast in photos, but the black version looks much nicer as a final product. I suggest using PETG for this instead of PLA, because PLA tends to warp very easily inside a hot car, even in a Tesla that does not reach temperatures over 105 deg F. Be sure to enable supports in your slicer. There's a section on the back/bottom that needs support during printing.

This item takes advantage of the cable route that's built into Jeda's own spacer. I'm not using a charging cable, so I might as well get some function from the irregular shape of the spacer where a cable could be routed; doing this allowed me to make my iPhone mini spacer/holder that will not move from its ideal position.

I use a thin case with my iPhone mini. If yours goes naked, this thing still works great. If yours is in a thick case, this won't work and you should think about your terrible choices.
