Math 3D Net Manipulatives

UPDATES:

April 19th 2026: 2 new 3D Nets have arrived by request! There is a new profile uploaded that contains a Square Pyramid, and a Irregular Triangular Prism! I have also cleaned up the model and profile descriptions and removed all references to the old hinges that aren't used.
Feb 23rd 2026: 2 new 3D Nets have arrived! There is a new profile uploaded that contains a Cylinder and Cone. This should round out the 3D Net set pretty well!
Feb 17th 2026: 3 new 3D Nets have arrived!! There is a new profile uploaded that contains a Rectangular Prism, Rectangular Pyramid and Triangular Prism. Cylinder and Cone are also almost complete!
Feb 12th 2026: I have uploaded a new profile, version 2 of the Cube and Triangular Pyramid. The hinge is now more durable and easier to print than version 1. I also removed the closing tabs, and version 2 manipulates much better, so they fold tighter than version 1. I am also working on more 3D Nets as well, they will be coming soon!

I wanted to share some 3D Net manipulatives that I made for a teacher friend to help her students visualize a 3D object unwrapped in 2D space

There are currently 9 nets!

Printing Tips:

Prints very easily, no supports, low filament cost, lightning infill. You can adjust as desired.
The hinges are meant to only go in ONE direction when closing the net. You can normally tell the right direction because there is a chamfer on the inside edge. The cylinder is the only one that doesn't have this, but it folds inward from the build plate orientation.
Make sure you have a clean build plate, the first layer on these are important!

I hope this helps more teachers and kids out there. Teachers are undervalued, but we appreciate you over here!
