Can I scatter my mosaic pieces away from each other by exactly 3mm with one command?

Is there a way to scatter the pieces of this mosaic.
Where all the pieces are 3mm away from each other?
Or really 2.84mm kerf thickness.

I've stepped thru each piece and moved them perpendicular to the piece right next to it.

But for some reason it always comes out slightly off.

Can I scatter my mosaic pieces away from each other by exactly 3mm with one command?

Not ramdom.

I didn't want to use the word move nor explode to keep from confusing it with sketchup commands.

Use F for Offset on all pieces
then Scale to return to original pieces sizes. (?)

Mosaic
offset each piece by 1.5mm
Giving kerf width of 3mm

Removed 3mm kerf
(not scaled)

Reassembled

shows 8 areas of overlap.

interesting

Proving every single one of the 16 outside pieces would need further adjustment.
