The model
The toggle anchor works on the snap-toggle principle: a bolt (Ø 9.4 × 40 mm) is pushed through a drill hole of at most 1 cm and tips across behind the wall. A strap pulls it against the wall, and the screw holds it there.
Everything is produced in a single print as print-in-place: bolt with pin hinge, strap and cap are already connected, nothing to assemble. The screw (4 mm) cuts into the 3 mm core hole.
Six anchors lie on the plate. The 0.3 mm clearance in the hinge and the free tilting from 0 to 90° have been checked by calculation.
