Now I created this model, converted it to 3ds and imported it but it dont works. I made an easy RGB-W fixture. RGB linked to the new model and W linked to an existing cylinder model. It will not work. https://gdtf-share.com/gdtf.php?page=home&manu=User tests&fix=led spot-wash&rev=3141

It don´t works. @petrvanek How did you make the rings for the Robin 800X MH. I think I need the same. I need a geometry with: Length 83mm Width 70mm Height 10mm and a middle hole of 38mm How can I make this and import this?
