For large hands. Brim recommended.

This design is for Nintendo Switch Joy-Cons. It is modelled after a 3D scan of an impression made with silly putty. I have used it for weeks and it’s very comfortable. If you've ever sat with a kid on your lap playing games together, you may know the value of having the joy-cons separated. It is also more relaxing to sit in a recliner with your arms on the arm rests.
My hands fit mens large sized gloves slightly snug (for size reference.)
These grips are not as comfortable for small hands.

This print needs a brim because it is printed vertically and the bottom area is not very large.

3D scan with Capture app by Standard Cyborg (iOS) an iPhone with FaceID is required. I scanned the Joycon with the silly putty attached to it. Exported from Standard Cyborg's website (sign-up but still free) as a .ply file. I edited that point cloud file in MeshLab to reduce the number of points then I created a solid surface using Screened Poisson reconstruction. Exported to .stl and imported in Meshmixer. Deleted irrelevant areas of the mesh and saved. Then imported into Fusion 360 as a mesh and overlaid a Mesh surface and matched the mesh manually. I had the attachment design already from another design so I used that with a trim body I created to make room for the Joy-con. Right side was just a mirror of the left.
