Atomos Shogun 7 Mount for Sony NEX-FS700

<p>A couple of years ago, I purchased a Sony NEX-FS700 second-hand for some random filming projects. However, I did not actually receive the rosette handle for the camera. Leaving a bit of a void in the overall look of it. Initially, I created a small adapter to fit a Atomos Shogun 7 to a tripod (seen <a href="https://www.prusaprinters.org/prints/122026-sirui-vh10-rosette-adapter">here</a>, for the curious among you). However, the empty rosette kept bugging me and I kept thinking that it was the perfect location to mount the monitor. Thus, after a while I designed this forked arm to hold it instead.</p><p>Quite a few parts of this design were carefully considered to make it work with 3D printing, as an example:</p><ul><li>The orientation of the prints were carefully chosen in order to maximize the<br>&nbsp;strength of the arms. They *would* hold on to rather expensive camera gear after all.</li><li>In order to allow smooth turning of the monitor, a pair of FR188ZZ bearings<br>&nbsp;were used.</li><li>A pair of M3 plastic inserts were used along the sides of the bearings to<br>&nbsp;ensure that the monitor could be friction-locked to stop it from turning when necessary.</li></ul><p>The prints were all made in carbon-fiber reinforced PETG, again to ensure that it would be as strong as possible. Although I am pretty certain almost any other filament would work given how strong the parts turned out.</p><p>Initially, I had intended to print the Hirth joint itself, however, FDM printers cannot really reproduce the details needed to create a functional Sony-style Hirth joint; the teeth are simply too small. SLA and SLS printers should be able to reproduce the details needed, but I doubt they would be able to withstand the required forces to be appropriate in this case. For that reason, I opted to purchase a compatible joint on <a href="https://www.amazon.se/gp/product/B07PSGNQDS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1">Amazon</a>, instead.</p><p>However, I have also added a model of the Hirth joint that should fit should you want to try it but please note that this has not really been tested; I don't have access to SLA or SLS printers and as such I have not tested anything beyond a quick fit inside of FreeCAD.</p><p>All in all, this model uses:</p><ul><li>4 + 2 M3 plastic inserts.</li><li>2 FR188ZZ bearings.</li><li>2 Shorter 1/4 inch (UNC) counter-sunk hex bolts.</li><li>2 M5 Screws. &nbsp;</li><li>4 + 2 M3 screws.</li><li>1 Sony style Hirth joint.</li><li>1 Long 1/4 inch (UNC) counter-sunk hex bolt.</li></ul><p>I don't really have any recommendations or necessary lengths available for the screws: I had to trim down a number of the ones I had on hand to ensure that everything would fit properly, but I could measure the final dimensions if someone out there wants them.</p>
