Me too but sometimes there is no other options (i'm probably not good enough to avoid post-processing ;) )

Like @Klaus I find this document a really good base ... I like it

The next work is to optimize the form of the snoot to concentrate the light in the middle on a point of 30 mm You see the iris in the middle in red

38 mm diameter it's not so big... I made a snoot 100% 3D printed The main problem was to make it watertight and to be able to rotate the iris in the snoot. It work now I have to optimize the weight and reduce the loss of light to have a maximum power for the position lamp and also enough when the hole are only 2 mm

The link doesn't work...

You can see it's not a 90° connector but a 180 ° ;)

I hope this give you some ideas

I ve no time for more info over the Retra connector now but will give you more details if you want later If someone want the 3D STL file for the connector ask. I fogot to say to part are printed with TPU only the bolt is in PETG. It is easy and fast to mount and unmount It is a very important point in my setup then the fiber is going throug the arms.. The idea is to protect a maximum the cable

here at the Retra side

Yes yes it's comming.. I needed to restart my PC (sometimes when it don't want...;) The Onedrive sync had a problem. Yes I know with Retra I show you an other connecter for it Mounted on my Isotta housing

Hi after the technical problem I had during the first attempt I start a second time (Thanks again to @RichN for the help ) I make a model with Autodesk 3D Fusion the same As you can see I have 3 green parts 1 for double fiber 2 for single fiber but with 2 different diameter

Absolutly.... but Donate is for me a better way as paying for each photo. The target is clear "I support the site I donate" if I pay for participating to the contest.... hummm, it is to win or to help the site ?

Suggestion : In the shop all dimension are in inches. It's ok , but having also the cm can be good for the members not familiar with this unit (like me ;) ) If you have a topic for bugs or/and wishes feel free to move this post. ;)

found it in the shop... why not to put the "Donation" visible from all at a good place. I didn't see it before.
