I recently upgraded my Zonestar Z9M2 to a Duetwifi board and could no longer use the display that came with the printer. So I broke out an old Galaxy S7 and a set of calipers and made a charging stand that bolts right to the 2020 extrusion on my printer!
After my first version I decided to do some small tweaks and share them here. All versions are designed to have the phone on its side. If I get enough requests for it, I may do a V4 that allows the phone to stand up. Here are the differences between the versions:
V1- has open ends on the right and left side so that it can accommodate phones that may be slightly larger than the S7
V2- has small walls on the right and left to make it harder to knock the phone off the charger
V3- is a standalone charger designed to sit on a desk instead of being bolted to 2020.
Here is a link to the $3 Qi charger that this is designed for. I have bought 4 of these and they work great!
I did not need any supports to print these!
