Scaling for laser or 3D Printing

Hi I’m new to rhino and having a bit of challenges scaling my model down to 3D print. It is a12 meter box but I need it to be 0.3048m squared.
Any help would be awesome

Hi @Darnell_Whymns to scale your model to 0.3048 m squared, you should scale your model by factor 0.046 (square root of 0.3048)/12, that is if it were 12m long.
The model you attached however is 1198 mm long.
