Three tiny steps

From “what if?” to ready-to-print.

No CAD shortcuts, no mystery settings. Just a focused path from model to studs.

Open your model

Choose a 3MF or STL. It opens in your browser and is never uploaded to StudBloom.

Pick a flat face

StudBloom finds horizontal, vertical and underside faces and shows which ones have room for a full 1×1 footprint.

Tune, preview, export

Adjust fit, inspect the live stud layout, then download 3MF or STL directly in your browser.

Made for 3D printing

From selected face to slicer-ready 3MF or STL.

StudBloom creates real stud geometry, not just a visual preview. Tune the connection for your printer and material, then export the result locally.

Real stud geometryThe studs become part of the exported model and are ready to slice.

Tune the physical fitAdjust diameter, height and tolerance to suit your printer and material.

Export 3MF or STL locallyThe finished model is built in your browser and downloaded straight to your slicer workflow.

Private by design

Your model never leaves your device.

StudBloom opens, edits and exports the geometry locally in your browser. No model, derived mesh or filename is sent to StudBloom.
