Phone holder for Mapillary mapping from public bikes

Final results are here:

---

Bill of materials:

• 3d printed part — two options
  • MakerWorld — Tough claw to quadlock mount adapter for Mapillary — one click printing for Bambu studio or orca slicer
  • or onshape document to manually prepare for printing
• phone with quadlock case
• any quadlock compatible vibration isolation part and locking mount — for example this one
• RAM MOUNT Small Tough-Claw — RAP-B-400U

How-to:

1. Unscrew ball joint from the RAM claw — keep the screw
2. Disassemble the adapter bracket for the quad lock vibration dampener
3. Use the nut from the quad lock adapter in the smaller hole and screw in the vibration dampener to the star pattern part
4. Use the screw from step 1 to attach the 3d printed part to the claw
5. Attach quad lock mount to the vibration isolator
6. You are done!

Caveats:

1. Optimized for pixel 3a XL, other phones might have parts of the mount in frame
2. 3d printed part limits vibration isolator range of motion — can remove some part of it for clearance
3. Phone can only be mounted before screwing the tough-claw to the bike
4. There is little clearance to mount the phone to the quad lock mount
5. This is a very rigid mount and will create jello effect on video on rough roads
