Yes, you can. You can print as many as you need.

Yes, as long as those tracks are used in LUG or personal layouts. The LUG / LUG members cannot sell the tracks unless they have our written permission, see commercial use.

Yes, as long as the compensation is to cover the production costs (cost of the printer, material, electricity, etc.) Selling the tracks with profit is commercial use and requires our permission

Yes. The same rules as those for LUG/LUG members explained above apply.

If you ask us first and get our written permission, you can. In fact, we encourage 3D print fans to start printing and selling our tracks to the AFOL community.

No, we provide the models free of charge. If you’re grateful that we provide them or you want to support this project you can give us a donation.

Yes, there is a 3% commission on all sales. For this you get a 4DBrix™ membership so you have access to all models and you get a marketplace store on our website so sell your products. There are no other fees.

Because we want to prevent abuse:

• We’re looking for enthusiasts to provide prints to their local/the AFOL community. We will not allow our models to be used in a way that we believe in not beneficial to our community, or by entities that have harmed the community in the past.
• We want to protect the consumers from makers that provide sub-quality prints or any other form incorrect customer service. You can find a list of approved resellers on our website.

If you sell the tracks, you cannot remove the 4DBrix brand name. If you print the tracks for personal use, you can, but we would appreciate if you don’t.

No, you cannot, but you can send the download link to your friend. This project is partially funded by the web traffic generated with the website. Distributing our models reduces the traffic to our web site and undermines the viability of this project. So if you want to share our models, please provide a link to the corresponding download page on or website.
