Monzana Trockenbauschleifer Gelenk
You need some normal Drills and Special Drills and the right rivets and rivet gun!
The holes are not in the file, because i wasn't able to coordinate them in that particular Shape.
What i do is: Take a Wire or long but small Screw, push the Print over the Frame, make it hot, way over 300°C in my Case i print with PA so i aimed for 400°C and push the Wire/Screw from the inside to the outside.
Once i got my holes, i drill them to the right size.... glue the print on the frame and rivet it...
in the empty shape for the seal will be filled with Duplicating silicone like: https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fwww.dension-dental.de%2Fwp-content%2Fuploads%2F2023%2F06%2F59252.jpg&f=1&nofb=1&ipt=7162f3b553f5cc434b9042bf0ac11200b949b458d7e841fe98474e839dc96f61&ipo=images
the adjustable metal hinge as well as the metal hook will get screwed afterwards, like it was before installed.
Have Fun.
