PRS-350 [Request] 3D scan or exact measurements of Sony PRS-350 / PRS-650 stylus for 3D print

[pratjic]

Hi everyone,
Since finding an original replacement stylus for the Sony Reader PRS-350 (and PRS-650, as they share the exact same stylus) is nearly impossible nowadays, I’m planning to model and 3D print one myself.
If anyone still has the original stylus and an iPhone/iPad (or just a ruler/calipers), could you please help me out with either of the following?
1. A quick 3D scan (Photogrammetry / Object Capture):Note: Rear LiDAR alone isn't detailed enough for such a thin object, so Photo/Object mode works much better. Free apps like 3d Scanner App (by Laan Labs) or Scaniverse allow free .STL or .OBJ export without a subscription. Tip: Please place the stylus next to a ruler or a coin on a matte, textured surface (like a wooden table) so I can calibrate the exact 1:1 scale.
2. Or simple reference photos + measurements:Top-down and side-profile photos of the stylus lying flat next to a ruler (to minimize lens distortion, please take the photo from a bit further away and zoom in), plus exact total length, shaft diameter, and clip/latch dimensions (ideally measured with calipers).
Important details I need to get right for a snug fit in the reader's slot:
Shape and thickness of the top clip/cap that locks into the housing.
Any small grooves, notches, or tapering along the body that hold it in place.
Once I clean up the mesh and test-print a working version, I’ll gladly share the final .STL file here for the community!
You can post it here or send the files/photos directly to my email: pratjic@gmail.com
Thanks a lot in advance!❤️
