The magnetic part which was supplied did not fulfill my expectations.
The set was that kind that after fixation on the ceiling (3M-VHB-pad) or screw and wall-plug (my choice) you neede to beat around the bush in order to find the right orientsation holes and snaps. What a waste!
I designed a simple disk with one screw hole in the middle, three Ø10x3mm Neodyms around, 0.6mm under the final top-layer (versus smoke detector.PDesigned in TinkerCad, printed in PETG on my MK4.
Once the plate is mounted to the ceiling you absolutely easily hold the detector to the plate, it snaps in automatically. E.Z.
100% better than supplied solution.
