Use a modifier mesh to strengthen only the area of a 3D print that needs it

This offers a measurable way to cut time or material while keeping clamp jaws, mounting tabs and threaded-insert pockets strong.

What to do: Try a small test bracket with extra walls only around fastener holes, and compare sliced material use with the all-over stronger profile.

Use a modifier mesh to strengthen only the area of a 3D print that needs it. PrusaSlicer supports modifier meshes and height-range modifiers. They let you assign different infill, wall counts, speeds or layer heights to selected regions of one model instead of changing the whole print.
