Mouse: drag to turn the view, right-drag or two-finger drag to pan, scroll to zoom.

Ask AI (optional): connect an AI service you use, or one on this computer such as Ollama, and ask about your model. It is sent the check report and your question, never the model, and nothing changes until you press Apply.

MeshRight

This only asks GitHub for the latest version number, once a day. Your models never leave this computer.

Clean up

Checking what needs doing…

Still broken after cleaning? Make Solid rebuilds the whole model as one closed solid. Detail finer than about 0.2 mm is softened.

Which printer do you use?

MeshRight uses it to check the model fits, and to suggest sensible sizes. You can change it any time.

Best way to print

Trying different ways to place it…

Support amounts are estimates for comparing options; your slicer makes the real supports.

Make a bust

For a scan of a head, or head and shoulders. Closes the opening at the neck, cuts the ragged bottom off flat, adds a base and sizes it.

Stand the head upright first. If it is lying down, use Which way is up?

Make a part

Turns the blue area into a solid piece shaped to fit it, such as a pad, a grip or a cover. It opens as a new model; this one stays as it is.

3MF in colours

Groups the scan's colours into a few print colours and paints every triangle, so Bambu Studio, PrusaSlicer and OrcaSlicer open it ready for a multi-colour printer. In the slicer, give each colour a filament.

Fewer colours give cleaner areas. Four suits most scans; use as many as your printer has filaments.

Hollow for resin

Makes the inside hollow to save resin, keeping walls of this thickness, with drain holes at the bottom so trapped resin can run out.

Ask AI

Ask in your own words, for example "will this print?" or "make it 15 cm tall and fix it". The AI sees the check report, never your model. It can only suggest changes; nothing happens until you press Apply, and each step can be undone.

Connect an AI

Optional. MeshRight works fully without it. Use a service you already pay for, or a free one that runs on this computer (Ollama, LM Studio). Your key is kept on this computer only, in a file only you can read, and is never shown again.

Address (only change for a custom or local service)

Wall thickness

Measuring…

Give it thickness

Turns an open surface, such as a face scan, mask or relief, into a solid shell. The scanned surface stays as it is; the thickness goes behind it.

2 mm suits most filament prints. Use at least twice your nozzle size.
