An add-on camera grip for a phone (like my previous model) is great, but it's still hella awkward to get your thumb in position to press the shutter button on screen...
So I made this - a cameraphone grip that includes a physical shutter button that uses a cheap off-the-shelf bluetooth camera remote.
I've included multiple sizes of grip (plus some left-handed versions), but the 75mm size should be a good fit for most phones.
BOM

Wire, solder, etc | Recommend thin AWG28 wires or smaller |
Build Instructions
1 Print with supports
The STL file for the grip body is pre-configured at the best angle to minimise overhangs. I recommend tree supports for the bottom of the grip, and for selected areas:
2 Install switch
Use the included wrench to install the pushbutton switch into the grip body
3 Solder wires to Bluetooth remote
Disassemble the Bluetooth remote.
Note that the remote as an "iOS" and an "Android" button. The PCB has 4 test points marked "VIN", "ICE", "GND", and "GPIO7". My probing with a multimeter shows that ICE is connected to the "Android" button, and GPIO7 is connected to the "iOS" button.
So if you want to use this with an iOS device you would connect the grip button to GPIO7 and GND, or if you want to use this with an Android device you would connect the grip button between ICE and GND.
I recommend connecting the battery and testing your remote by shorting the pins.
Note that the remote pcb has a slide switch for on/off. We'll just ignore this and leave the switch in the on position. In my experience the battery will last at least a matter of years, and when the button is pressed the remote will wake up and connect.
As I'm using an iOS Device, have soldered the wires to GPIO7 and GND:
I have added a dab of non-acid RTV silicone for strain-relief, but hot glue or anything else should also work

5 Assemble, add battery, test
6 Add velcro
