I used a Puck.js to make a remote shutter release for Sony cameras. You can find the repository on Github. This is a nice enclosure with a switch for it.

You'll need PETG and TPU 90A to make the best of this, as well as the following hardware:

• 1x - Puck.js board
• 1x - EG1205 switch
• A few cm of wire to connect:
  • Off leg to GND
  • On leg to VCC
  • Middle leg to D28
• 2x - M2 6mm flathead screws
• 2x - M2 8mm screw inserts
• 2x - M3 4mm screws (non flat)
• 2x - M3 4mm screw inserts
