We designed this to mount cell phones of any size to camera tripods, even if you have a phone case and a pop socket attached. The best part is that it is almost 100% 3d printed! You just need a 1/4"-20 hex nut and we recommend adding two short adhesive foam strips to protect the phone from scratching and increase the grip.

This should work on most different types of tripod plates (Oben, Ambico, Manfrotto, Arca Swiss, generic ones, etc) but you should definitely check the stem.stl file to verify this (there are +4 variants now, and we can add more based on feedback).

• The base version has a pocket to fit the 1/4"-20 nut and a slot for the alignment pin we see on some tripod quick-release plates.
• We've added two more versions where the nut can be replaced with threaded inserts
• And additional versions compatible with Arca-Swiss mounts (no inserts or hex nut required!)

If you print this, let us know! Tag us on Instagram and we will feature your print :) Or you can leave us a review here. It really helps us improve our models 👍

Edits 16-07-2022: Added clamp_A_v2 and clamp_B_v2. Those are longer, to hold bigger phones. 06-01-2025: Additions based on comments (thank you all!)

• Added a version of the Clamp files with a grippy texture to prevent the phone from slipping in case you decide not to use foam strips (foam strips are still the recommended way to use it)
• The threads are now ACME profile, which prints easier and is a lot stronger
• Added 4 new versions of the Stem:
• Compatible with CNC Kitchen's 1/4in threaded inserts, both the short and long variants.
• Compatible with Arca Swiss clamps, for 38 and 26 mm dovetails.
