Here I've collected some of the questions that I get quite often:

3D printer company/filament (plastic) producer, can I use your free models for marketing?

Yes, as long as I get credited with my name and website (olasundberg.com) you can show images of prints on your companies. You can also use actual 3D prints on fares/expos as long as I get credited in the same way.
However, you CANNOT: sell any 3D prints of my models, sell my digital model, change my designs in any way, use the images/3D prints without crediting me.

I want a character for 3D print, it would be great if you could make one really, really cheap?

That would be fun but it does take time and I still would like to get paid for my work.
To make a unique design for a character and to make it ready for print, takes anywhere from 15 to 50 hours. Depending on the complexity of the design.
If you are still interested please contact me!

Can I get the complete license for a character that you've made?

Yes you can, but it's an additional cost if you want to own the license. If you pay me for the design work I still own the copyright. You get to use it for a set amount of prints or for a limited time. Send me an e-mail and we can talk!

I am a student and would like some feedback on my portfolio or just some thoughts from you on how to pursue a career in 3D.

If I have the time I can take a look and give you some short feedback.
