Buddy3D Cameramount XL

Holder

After printing remove the support, melt in the threaded inserts M3 (2 pcs.) and press in the magnets Ø6x3 (8 pcs.). The height stop is bent 90° and snaps into place (see picture)

Camera mount

Remove the support, drill out the holes if necessary; in my case they have become a little too small.
 

Connect both parts with M3 screws (2 pcs.) (M3x10 to M3x20 possible).
