3D models for 3D printing
Simple modelling in millimetres and an export your printer accepts without repairs.

Exactly in millimetres
Switch units to mm, draw rectangles and circles and pull them up. Fillets, chamfers and holes are done right in the app.
Hassle-free export
STL at the scale you choose, each object separately, or 3MF with colours and correctly oriented faces. The model check finds open solids before you print.
House and landscape models
Scale a house or terrain down to 1:100 or 1:200 and print it as a model for a client or a competition.
What helps you
- STL export to scale
- 3MF export with colours
- Lay flat on the largest face
- Model check and repair
- Every object as its own STL
- Back faces in colour
Frequently asked questions
Which slicers read the files?
PrusaSlicer, Bambu Studio, OrcaSlicer, Cura and others read STL and 3MF.
How do I print a model of a house?
Export STL at 1:100 or 1:200 – the sizes are converted automatically.
What if the model isn’t closed?
Run Model check and Close holes. Back faces shown in another colour reveal where the problem is.
