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 here, 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.
Quite a few parts of this design were carefully considered to make it work with 3D printing, as an example:
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.
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 Amazon, instead.
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.
All in all, this model uses:
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.
