From known geometry to a printable file.

Three inspection plates follow the real workflow from case selection to an immediate file handoff.

  1. Choose a case

    Begin with a supported hard-case profile and its known interior dimensions.

  2. Arrange known gear

    Place, move, rotate, remove, and inspect supported profiles in the browser.

  3. Export when ready

    Download the STL immediately, then choose how you slice and print it.

Start with geometry, not a photograph.

Apache 3800

Upper and lower inserts

Arrange each layer separately and export its own STL.

Compatibility and printing details

Insert model dimensions in millimetres; not the case’s exterior dimensions.
InsertWidth × length × depth
Lower376 × 266 × 53 mm
Upper379 × 269 × 53 mm

Dimensions describe the insert models. Physical fit depends on your case, material, and print settings. Compare all supported cases.

Revise before the irreversible step.

Move through the layout digitally before committing time and material to a physical result.

StashGrid interface annotated with the product's main points of difference

Supported profiles

Start from catalogue geometry for supported gear instead of photographing an outline and correcting it by hand.

Editable source layout

Use perspective and planning views, then move, rotate, undo, and revise. The layout persists in this browser.

Immediate file handoff

Export the STL when the layout is ready—without entering a quote, proof, fabrication, or shipping queue.

A file you control.

STL download is immediate. Slicing, material choice, printer settings, print time, and the physical result remain your next steps.
