StashGridDesign your insert

Case insert guides.

Practical guides for deciding how to organize a hard case and for printing the insert you design.

Replacing pick-and-pluck foam

Compare the ways to replace worn factory foam: reinforcing it, replacement sets, cutting your own, made-to-order foam, modular grids, and 3D-printed inserts.

Printing your case insert

Take an exported STL through scale checks, build-area planning, split prints, material choice, and a test fit.

Start from your case

Each supported case has its own page with insert dimensions, layer details, and print planning notes. Browse supported cases or open the designer.
