External Monitor Mount for iPhone Continuity Camera

Continuity Camera is a great new feature for the iPhone, allowing you to use your phone as a webcam with super picture quality. 

Here's a universal phone mount to use your iPhone and Continuity Camera with any external monitor. The monitor mount can be adjusted to your monitor's shape to stabilize the mount. Use the tightening screws to fix it in the optimal position. 

Three options to mount the camera:

• A MagSafe holder. Just snap an Apple MagSafe charger into the holder and let MagSafe do its magic.
• Adjustable clamp. It should work with most if not all phones and protective cases. 
• A simple box to drop the phone in. More convenient than the clamp. 

UPDATE 6/26/23: Added MagSafe Holder.

UPDATE 12/4/22: I realized that while the phone clamp is a good way to secure phones of every size, sometimes it's just more convenient to drop the phone into a simple box. So here it is, the simple box. 

Bill of Materials

4x M3 hex nuts for clamp or MagSafe options, or 5 nuts for box option.

2x M3nS thin square nuts. Not required for box option.

2x M3x60 fully threaded screws (e.g. https://amazon.com/gp/product/B07RRGKZLM).

2x M3x14 screws (from spare kit).

1x M3x25 (from spare kit) for clamp option.

1x M3x20 (from spare kit) for box or MagSafe option.

Print Instructions

I strongly suggest using PETG or ASA even though PLA may work too. See attached 3MF files for parts orientation and suggested settings.  For the monitor mount, use the file “monitor mount.stl” to (preferably) print all parts in place, or use the files called “segment x.stl" to print each part separately.  For options to mount the phone, choose between “magsafe holder”, “phone clamp” or “simple box” and follow the respective instructions.
