I modeled this part to attach a Yi home camera to my printer for remote monitoring since the Elegoo Matrix app doesn't like to work very well.  This was made to fit an Elegoo Centauri Carbon 2 but will likely fit the Centauri Carbon assuming the door screws are 25mm apart.  You'll need two M3 x6mm screws to attach it since the factory screws are very short.  I printed in PLA with the angled face upward with supports.  I tried printing angled face down which gives a better surface there, but the visible face of the mounting tab didn't turn out well.  Step file is attached for adjustments if needed - modeled in Onshape.
