Auto arranging objects into build chamber for printing

I’ve been told about work about a plug in that a previous employee used, which could take all selected objects and arrange them (tessellate, flip, array etc) into predetermined build chamber parameters for 3D printing. Nobody who currently works here has used the plugin, or knows what it is called and I have no idea what I’m looking for.

Is there an existing plug in or script that might be used for this?

Thankyou!

Hi - that sounds like the functionality of software that is shipped with a 3D printer and not a Rhino plug-in.
