Way 1 to create a cool laserable Voronoi pattern

Draw some path (convert your rectangles/objects to path. We need it later for destructive clip)

Create Voronoi

Detach the pattern

Adjust some sizes and adjust stroke width (e.g. 5 mm), remove fill

Convert contour to path → this keeps the original path in background and creates a new. Belonging to the selection we get different results using Destructive Clip

Way 2 to create a cool laserable Voronoi pattern

Draw some path

Apply Pattern

See the generated fill pattern

Covert pattern to object

Path → Division: Select the boundary path and the pattern

Combine to have one path
