Smoke alarm base

Spare part for a 10 years smoke alarm where a tab on the base has broken. The smoke alarm is made in China and was sold by Danish company "Harald-Nyborg". The diameter of the base is 91mm, the inside distance between the tabs is 80mm (each tab is 3mm wide, so the outside distance is 86mm). Just printed in generic white PLA using a default profile for the "Bambu labs A1 Mini" (0.2mm layers, 15% infill, support touching build plate), while the red one is a prototype printed on a Anycubic Kobra 2 Pro using 0.2mm layers, 10% infill and support touching the build plate.
