The frame does the job to add a spot for aqara opple below an existing switch. I guess the design is not 100% perfect, but it does the trick for me at least.
0.15mm structural
0,40mm nozzle
15% infill
Supports: recommended
Brim: recommended
Glue some 3mm thick magnets in the aqara room.
The magnets can be “hidden” by using a permanent marker with same color as your print.
The author remixed this model.
I combined these two models, took the Elko part from one, and Aqara from the other. I also did some customizations.
