HCDNA grabhole clamp

thingiverse

A support for the Rectilux Hardcore DNA (HCDNA) single focus solution. The idea behind the clamp is simple: on some anamorphic lenses, it's challenging to mount a single focus solution directly. Maybe you can't attach a front ring, or it's just too big to use one effectively. As the inner 75mm threads stay untouched, most scopes can be brought as close to the single focus as possible, leaving minimal room for vignette. It's also incredibly handy when testing many different anamorphats without re-mounting each time. You'll save yourself a lot of hassle and get back to work faster. INSTRUCTIONS The three holes around the ring are designed for countersunk head screws in m$, which screw directly into the threads of the HCDNA. It features two notches so you can mount the HCDNA in different rotations, making it easy to adjust as needed. The rail requires a 15mm rod clamp with either a 38,2mm or 35,5mm width - make sure yours is right, or get one that fits perfectly. The length is just enough to work within ARRIs standard LWS system, with an 85mm height. As the outer wall isn't super thick, be sure to use sufficient wall strength as well as proper infill; I used 40%. PETG is preferred over PLA, but I used PLA for this project.
