THE SMALL, PRACTICAL 3D WORKBENCH
From project files
to a tidy print handoff.
Open 3MF. Check the size. Export cleanly named STL files
with a manifest that keeps the whole batch in order.
Your models stay
on your device.
A clearer view of your next batch.
Add a 3MF file or open the sample to begin.
Ready. Start with your own file or our original sample.
Less file wrangling.
More making.
- 01
Open the project
Read supported 3MF mesh objects, units and component transforms on your device.
- 02
Check before exporting
Inspect the geometry and dimensions. Unsupported structures stop with an explanation.
- 03
Hand over an organised batch
Download STL or a ZIP of build objects with consistent names and a dimensional manifest.
Try the complete workflow.
All current tools are free during launch access. Pro is planned at $9 once for batch delivery. No payment is collected today.
Single-project viewing and merged STL conversion stay free.
- Up to 10 projects per batch
- Separate STL for each build object
- CSV dimensions and file manifest
- Local processing, no model uploads

What carries over?
Does conversion keep colours or printer settings?
No. STL contains triangle geometry only. Colour, materials, textures, support settings and printer profiles are lost. Keep the original 3MF if you need them.
Will the dimensions change?
Supported 3MF units are converted to millimetre coordinates, including component and build transforms. STL itself has no unit field: choose millimetres when importing it elsewhere.
Is every 3MF project supported?
No. This tool supports mesh geometry and the structures listed in the compatibility notes. Encrypted files, unsupported required extensions and malformed references are rejected. It does not generate G-code or certify printability.
Does splitting mean splitting every connected shell?
No. Delivery export creates one STL for each printable build item. Components within that item stay together, and their placement is preserved. It does not infer separate physical parts from connected surfaces.
Where are files processed?
In this browser. Models and their names are not sent to our server. Pro license activation, when available, contacts our payment provider through our server. Privacy details.
