Choose fileHollowing works best on watertight meshes (run mesh repair first if needed).
What is it? Mesh Hollow offsets a watertight mesh inward to create a shell with a chosen wall thickness, reducing material for 3D printing. Export the result as STL.
TL;DR: Create a hollow shell with a set wall thickness for printing.
How to use
- Open a watertight model.
- Set the wall thickness.
- Preview the shell and download STL.
FAQ
Does the model need to be watertight?
Yes — hollowing requires a closed mesh; repair it first if needed.
Is it local?
Yes, the operation runs in your browser.
Limitations
- Thin walls relative to detail may self-intersect.
- Supports one enclosed volume reliably.
