How Do I Merge Two stls for Dual Extrusion?

[inventabuild]

Attached are two stl's (in zip format because stl's can't be uploaded to forum) that are part of the same model created in freecad. When I open them in KISSlicer they are side by side; however I need the numbers (1st stl attachment) inset into the surface of the table top (2nd stl attachment) just as they are in the freecad before I broke the model up into two stl's. The pic entitled "table with numbers inset" shows a visual in freecad of what I'm working with.

Does anyone know how to merge two stl's so I can use dual extrusion to print each stl of the model in a different color?

Open them at the same time: with the file selector dialog, CTRL-CLICK on the files you need to merge as a single print.

Hi,
first of all you have to check the option at the menu bar: Preferences//file handling//load multiple stl's into a single model.
See the screenshots attached for further explaining. EDIT: the upload of the pics was in the wrong order, so start with the lowest screenshot
Of course you have to tweak the printer settings / Gcode Prefix / select and deselect extruder as well, according to your firmware.
