Requirements and limitations

Removable divider plates print flat and seat in shallow floor tracks; separate roof-down clips join their top edges. Stackable lids may need supports in the supplied orientation. Fit, retention and stacking stability require test prints. Commercial use of MiniForge tools requires an active DIAMOND membership on Patreon. Third-party artwork and icon licenses still apply; membership does not grant rights to someone else’s artwork. Read the Terms of Use before selling prints.

Frequently asked questions

Are dividers removable?

Choose Built-in for a single printed tray, or Removable for separate flat plates that seat in wall grooves and floor tracks, with small removable clips at branch joints. You can split only one selected compartment.

Can I save my design?

Yes. Save and load editable JSON projects. The last valid draft is also saved locally in your browser.

What clearance should I use?

Start at 0.25 mm per mating side and print the free fit-test pieces. Printer and filament differences can require adjustment.
