Model license
The models we publish are free. These are the rules for using them.
What you can do
Download, print and use the parts, at home or at work. Modify the model to adapt it to what you need. Give away the parts you print.
What needs authorisation
Selling parts printed from our models. Publishing the model, modified or not, on another platform. For either of these, write to bruno@pontoquatro.pt. We usually say yes, and quickly.
What you can't do
Resell the model file. Distribution of the file is ours. Present the model as your own.
Attribution
If you show the parts in public, we'd appreciate a mention of Ponto Quatro. It's not required for personal use.
No warranty
The models are provided as they are. We tested them before publishing, but every machine is different, and we're not responsible for print results on equipment we don't know.
