iPhone 17 Pro case with the Hex Connect mounting system

Updated at source: Oct 4, 2025

Model information

This is an iPhone 17 Air ultralight case made to work with Hex Connect mounts. The non-XL variants can be printed with less than 22g of filament!

Made to be printed in rigid plastics, ideally ABS or ASA for their toughness, though PLA will work fine too.

The three provided variants are:

Standard with Magsafe - Connects to the standard Hex Connect connector. Has a recess for mounting a thin Magsafe metal sticker with ID of 45mm and OD of 55mm.
Standard without Magsafe - Connects to the standard Hex Connect connector without the Magsafe recess.
XL - Connects to the XL Hex Connect connector. It's too thick for proper Magsafe functionality so no magsafe recess included.

Standard vs XL pros and cons:

Connector	Pros	Cons
Standard	Thin enough for proper Magsafe support (2mm) Slimmer case is more convenient for everyday use Allows use with Magsafe mounts using a case mounted metal ring Probably stronger than you would expect :)	Not as strong as XL
XL	Strongest connection for high intensity activities	Thicker case is less convenient for everyday use Not Magsafe compatible
