Cool mod! Just to make sure, are you able to have your phone hold tightly to your mod even without sticking the Tetrax magnet part onto the back of your phone/case? Or is the mod able to hold the phone stably without it?
I doubt any of you will do this but... I'll explain anyway.
There are many holes that need to be precision drilled...
1. hole for the tetrax magnet that goes on the front cover of the wireless charger.
2. screw holes for the vent mount on the back cover of the wireless charger.
3. a hole for your phone case to have the tetrax plate which is only 9mm wide.
I took the 9mm plate and epoxy and glued it to a left over screen protector film.
Drilled a hole dead center of the phone case.
The circular plate fits perfect in the hole without protruding out of the case.
One note... I have a TPU case, and... thermal polyurethane is impossible to drill with a regular bit. I had to make my own bit using one of my wife's makeup pen thing... the cap was made out of metal... i had to heat it and make it a bit wider to 9mm then put some notches to make it into a hole cutter.
I drive pretty rough/fast... I have yet to have the phone come off the magnet.
I still plan to put finishing touches...
1. remove the rubber anti-slip ring from the front
2. fill the seam between tetrax and the front cover
3. sand down the front cover
4. plastic dip the front and back cover
5. add the rubber ring back on.
Once it's done it'll look real stealthy... it might seem like a lot of work, but my car literally has no place to mount a holder/charger anywhere. and I don't like putting thing on my glass, i hate suction cups.
