The DOME is an assembly of parts 3D printed in PLA plastic (Figure \ref{247613}) , together with low cost optical, mechanical and electronic components (Figure \ref{755424}). The original device was printed using an Ultimaker 2+ printer, and has been replicated using an Anycubic i3 Mega, a lower budget machine. Parts were designed using Autodesk software and can be printed without requiring dissolvable supports.
