This adapter allows you to mount the Logitech MX Ink MR stylus onto a standard 1/4"-20 camera screw.
It is designed for screws with a head height of 5mm or less.

The connection part to the stylus is offset according to the rotation axis image of the MetaQuestTouch controller and stylus, as provided on the official developer site for MX Ink.
This rotation offset is set based on the image to ensure proper alignment.

The primary intended use is mounting onto VR glove controllers or similar tracker mounts.
For this purpose, the adapter includes holes positioned similarly to those on the base of the VIVE tracker (used for securing pins), spaced at 45-degree intervals with a total of eight holes.

You will need a 1/4"-20 nut, an anti-slip sheet (1mm or thinner), and zip ties approximately 2mm-4mm in width.
The nut’s dimensions should be 5.0mm in height, 10.0mm across the flats, with a 1/4”-20 thread (here is the nut I used: https://www.amazon.co.jp/dp/B0BVQLV86C).

Current issues with the design are as follows:

• Overhangs are present, resulting in support material being generated. I am considering design revisions to improve printability.
• The high center of gravity may cause stability issues when used as a tracker mount. I am evaluating ways to reduce the distance from the base to the stylus’s center of gravity.
• The stylus’s attachment position on the holder is not yet precise. For now, please refer to the image provided and adjust accordingly. I am considering revisions to enable more accurate positioning.

If you have any suggestions for improving this design, please feel free to post them here.
