Print it at the size you want

STL or 3MF in millimetres, with a stand if you want one. Free.

Hewly turns a model into a print file at the exact height you type, in millimetres, with a stand if you want one. Making the file is free.

Step by step

1. Open the model. In the panel on the right, find Print it.
2. Type the height in millimetres — the model itself; a stand adds a few millimetres under it.
3. Choose No stand, Round stand or Square stand.
4. Tap Download 3MF (best for Bambu Studio, PrusaSlicer and OrcaSlicer — it keeps the millimetres) or Download STL (works everywhere).
5. Open the file in your slicer and print.

Good to know

• OrcaSlicer and Bambu Studio buttons open the model straight in that app, if it's installed. They open it at its saved size, without the height or stand you chose — download the file for those.
• Print files are shape only. Colours and textures don't go into them.
• Analyse model health (free) looks for gaps. If it finds some, the 3D print tool under Do more with this model (10 credits) makes one solid, closed piece.
