World Creator Program

We want to expand our selection of habitat themes to be as diverse and imaginative as possible. Because the habitats are 3D printed, the possibilities are nearly endless, truly limited only by our imaginations!

We are establishing our World Creator Program in hopes of engaging creative minds brimming with imagination across the world to help bring these slime habitats to life in the most interesting and exciting ways possible.

If you have an idea for a habitat theme that inspires you, please model it and send it to us! If we choose to put it into production in our store, we’ll give you royalties of 2% of the revenue from the kit perpetually!

When modeling, please keep printability in mind, ideally with minimal necessary supports. Also, we have a standard base plate STL that ensures your model will fit in our containers properly for production; please start with that and make sure no parts of your design go beyond the outer edges of the plate (86×156 mm) and that the entire model is not more than 75 mm tall.

Please contact us at support@slimeoworlds.com or via our Contact Us page with any questions and for the base plate STL file to get started on! Also, if you have no or limited 3D modeling experience but you’d like to learn, we can recommend next steps for you!

See below for the details of the royalty agreement. We cannot wait to see your designs and bring them to life!
