This clamp offers a strong support for anamorphic lenses. The diameter is roughly 70mm and therefore works with many lenses. I successfully tested the following scopes:
- Kowa Prominar 16H/8Z, B&H
- Sankor Type-5e
- Schneider Kreuznach Cinelux ES
- Sankor CompactCinemascope/AnamoPrime
- Iscomorphot 16/2x
ISCO Ultra-Star lenses should work as well, as a variety of other scopes

This build needs an M3 nut, washer and screw (~15mm). Attach as close to the front of the scope as possible.

I made three versions for different rod-clamps. 40mm is the width of my generic china brackets, but I also did it for Neewer and SmallRig blocks. If you are unsure about your clamp, you can just measure it and compare it to the beam-widths procided in the STLs name.
The longhole isn't as long as this support was made for common LWS heights with a bit of wiggle room :)

Prints well without support. Infill should be at least 30%.

I found this clamp to be very sturdy; however, 3D printing has many variables that differ in every setup. Only use if you are comfortable with these kinda setups, I don't take any responsibility for yours.

No support needed. At least 30% infill is recommended
