I created this extension handle for the Divevolk SeaTouch 4 Max uderwater housing case for smartphones (used in a smartphone to underwater camera review available here: https://www.youtube.com/watch?v=e0hcaPTtJE0).

It is very comfortable to hold with its large grip and is extremely strong and capable.
Please note: I designed it to fit the Divevolk SeaTouch 4 Max 'Expansion Clamp' so please bear this in mind before printing.
I printed it on the Bambu Lab X1 Carbon using the Bambu Lab PET-CF filament for the frame and the Bambu Lab TPU filament for the grip.
