Be aware before you sell
The base designs are stated as MIT, but community add-ons vary, and at least one MakerWorld file bars selling printed versions, so check each file. The core system is open, but sellers state they are not affiliated with Zack Freedman or Voidstar Lab, and one reproduces the MIT notice naming them. Etsy asks for your own original design, so a licensed file may not qualify.
