It fits this model - tested on EU .  Prints without support.  printed at 0.24mm, 2 walls (if smaller, simply make 3 walls, no infill).

You place the mount wire side first,  then place the KOPPLA in it, place the left or right mount on the other side (depending on what's handy in your situation) and mark where it needs to go.

Remove KOPPLA, screw the left/right mount, then place KOPPLA into wire mount with a diagonal and push into the open side of the mount.
