I needed the ability to mount my Windshield Wireless Qi Phone Charger to my Car's Air-vents, and everything I could find already either didn't seem strong enough, or wouldn't fit my style car vent. I made my own mount instead, and it's extremely strong, sturdy, robust, and simple to print.
My Original Windshield mount's connector is a press-fit design with a 17 mm ball on the end, and it kept slipping out of the slot, causing my phone to come crashing down while I was driving (not ok). Not only that, but since I drive a black car in the South, the phone would often overheat and pause wireless charging if the AC hadn't been running long enough which was quite annoying.
This design uses my Air-Vent Mount (look at Remix Sources for that) where I added a ~30mm extension and a 17mm Ball on the end to fit the original wireless charger. Now, my phone mounts directly to the air-vent, where it stays nice and cool, and Doesn't fall down :)
If your Wireless phone charger is similar to this one:
Then it should work with yours. It uses a 17 mm ball joint design for the pivot, and is a easy swap from OEM windshield mount to the printed one.
20-100% (I made it 100 as it was a difference of 10 mins of print time so why not ¯_(ツ)_/¯ )
It's very important to print this part out of a material that won't warp or deform with high-heat.
My car is black and I live in the south, where it's easy for the outside temperature to reach over 90 degrees a day. The inside of the car is hot enough to burn you if you touch it. If where you live doesn't get too hot, you 'may' be able to print it without problems in PLA, but I printed mine in PETG. This part would likely work just as well in ABS if you can print that. It's a small part, and therefore warping will have minimal to no effect.
Depending on your printer accuracy, you may need to use side-cutters to split the four rounded ends apart if they print fused together. It's not a big deal, and will split easily with a little persuasion, but it's something to keep in mind.
I designed it very quickly in fusion360. I have provided the .stl , and fusion360 archive project file so you can remix the part to your liking.
