Building a droid without owning any of the parts will run about $150-$200US. However many of the parts below are included in Electronic “Starter Kits”. STEM Teachers and Hobbiests may have many of these parts already on hand… Bulding more than one Dr01d has some cost savings as many of these parts come in packs of 3, 5, etc. Parts were chosen based on how common the part was and inexpensive parts. The goal was to produce a each Dr01d for a minimal amount of money and 3D print as much as possible. Parts can of course be substituted as needed.
