Parts and Supplies

This section contains all the parts necessary to build your very own mini-dome. The 3D printer is not included in this section. You will need a 3D printer to complete the project or have access to one for the printed parts. The parts list below provides the names, the amount needed for each part, and an approximation of the cost for each item. The link shortcuts direct you to Amazon, where you can purchase the parts if you do not already have what is needed. The project should cost around $100 to complete.
