DIN rail holder for Shelly Plus with Add-on

Remix of the model of peterk34 found on Thingiverse. See differences below.

Put a screwdriver into the groove of the spring to bend when attaching to the rail or for removal.

Printing

Mirror in the slicer if you want it the other way around. The one on the photo is mirrored.
Place it upside down, so the part connecting the sides in the middle will lie on the bed. Enable supports else the analog terminal window won't be as nice.

I recommend printing this in flame retardant filament suitable for this type of use.
