FVD-16A grabhole clamp

Last crawled date: 4 years, 2 months ago

A support for the Rapido Technology FVD-16A single focus solution.
The idea behind the clamp:
On some anamorphic lenses, it's hard to mount a single focus solution directly; maybe you can't attach a front ring, or it's just a tad too big to really use one. As the inner 75mm threads stay untouched, you can bring most scopes as close to the single focus as possible, leaving the least room to vignette.
It's also really handy when you want to test many different anamorphots without re-mounting it every time.
INSTRUCTIONS
The three holes around the ring are meant for countersunk head screws in M3, screwing directly into the threads of the FVD-16A. Just rotate the FVD how you like to have the markings :)
The rail needs a 15mm rod clamp of 38,2mm width (there are many sizes! Make sure yours is right, else get a fitting one). The length is just enough to work in ARRIs standard LWS system, 85mm height.
As the outer wall is not super thick, make sure to use enough wallstrength as well as proper infill; I used 40%. PETG preferred over PLA (I used PLA though)
