Your insert, explained.

What exactly is StashGrid?

StashGrid is a browser-based designer for custom, 3D-printable case inserts. Choose a supported case, arrange gear profiles from the library, and export an STL to slice and print yourself. You can move and rotate items, inspect the layout, and undo changes before exporting. StashGrid provides digital geometry; it does not manufacture or ship your insert.

Which case brands do you support?

The current supported profiles are Apache 3800, Glock Factory Case, Pelican 1170. Apache 3800 has separate Upper and Lower inserts, each with its own editable layout and STL export. Support is specific to these profiles; it does not imply compatibility with every case from the same brand.

Can I save my design and finish it later?

Your current layout is saved in this browser’s local storage. You can return to it in the same browser on the same device. There is no account-based cloud sync or saved-design library.

Clearing site data, using private browsing, or moving to another browser or device can lose access to the layout. An exported STL preserves the printable geometry, but it is not an editable StashGrid backup: the designer does not currently import an STL to restore its original gear layout.

How do I secure the printed insert into my case?

First check the printed insert in the empty case. Its fit depends on the case, material, printer calibration, and print settings. A friction fit is not guaranteed.

If attachment is needed, choose a method compatible with both the case and printed material, following the adhesive manufacturer’s guidance. Confirm the fit and access to your gear before using a permanent adhesive. For Apache 3800, preserve the ability to remove the upper insert and reach the lower layer.

What is the advantage of this over Pick-and-Pluck foam?

A printed insert lets you revise a layout digitally and reproduce it from a file. You arrange known gear profiles rather than cutting foam by hand. Foam may offer different cushioning, weight, cost, and impact behavior.

A printed insert is not automatically stronger, more protective, oil-resistant, or maintenance-free. Those properties depend on material, geometry, print quality, and use. StashGrid does not certify impact protection, moisture protection, or a universal physical fit.

Do I need tools to assemble the insert?

You need slicing software and access to a suitable 3D printer. Compare the exported model with your printer’s usable build area before printing. Keep the model at its intended scale so the case outline and gear cutouts remain the right size.

If the model does not fit after choosing an appropriate orientation, split it in your slicer. Plan and test any connectors or joints; a split print is not guaranteed to snap together without adjustment. Export each Apache 3800 layer separately.

What are the best slicer settings?

There is no single validated settings profile for every case, layout, filament, and printer. Start with the printer and filament manufacturer’s recommendations, then inspect walls, floors, overhangs, and bridges in the slicer’s layer preview.

Choose supports, infill, and surface settings for the actual geometry and intended use. Check material limits for your storage conditions and test the fit before relying on a full print. Physical print validation is still in progress.

What license do I receive with my export? What are my rights?

When you export a design from StashGrid, you are granted a Personal Use License.

What this means: • You Can: Print the file as many times as you like for your own personal use (e.g., for your own gun cases, display, or storage). • You Can: Share the digital STL file with friends (e.g., sending a layout to a range buddy). • You Cannot: Sell the digital file or the physical printed inserts.

Important Note on Sharing: If you share the file, the Personal Use restrictions transfer with it. The recipient is bound by the same rules: they may print it for themselves, but they are strictly prohibited from selling the file or the printed product.

Do you offer a printing service for those without a 3D printer?

Currently, StashGrid is a digital design tool focused on providing STL files for you to print at home. We do not sell or ship physical products at this time. No print-and-ship service is currently available.

In the meantime, if you do not have a printer, we recommend sending your exported file to a local makerspace or an online 3D printing service.
