I created this project in Shape3d and modified it in Blender. I was looking at a TNMT movie and decided to create a city scene with a sewer playset. All pieces are print ready and before my printer broke, I had printed several pieces. Their are no textures mareral as of yet, but if I manage to do some , I'll upload them. I hope you have fun with this and feel free to work your own magic with this. Enjoy.
