Summary

I printed a bunch of phone cradles last year when I got my Samsung S8 that used the USB-C to charge my phone. It was kinda finicky and if I wasn't careful, Id go to bed with the thing not charging. Going to work with a dead phone is such a nightmare... I actually had to talk to people a few times!

I thought I'd try a wireless charger next. I have gotten 10% better at Fusion360, so why not make one from scratch? I also like the idea of a speaker reflector to boost the volume a smidge.

I also wanted to try to make a version that didn't require supports, so I added fins to the speaker horn to make supports unnecessary if you print it upright on its base.

I set this version up to fit my Galaxy S8 with Otterbox case, so it will fit any phone smaller then 76mm wide and 14mm thick. If your phone is wider you can just stretch the X Axis, and if you don't use a case you may want to shrink the Y axis, as the hole for sound cavitation is 5mm wide. The sides of the cradle are 8mm on each side of the phone and the phone hole is 76mm wide.

To charge wirelessly I just took apart a $3 eBay QI charger. Ive taken a bunch of these apart over the years, and they tend to have the same electronics, a circle to charge and a little board to control it.

I installed a charging app on my phone and moved the antenna around on the back of the cradle. I glued it down with some hot glue where it was giving the best charge, . Then I threaded the USB wire through the hole at the bottom of the back plate. Then I secured the back with two small #6 wood screws.

If you just want the cradle, I have included the full version, as well as an older version I made that ended up being too short to use as a QI charger.
