As a fan of Lego’s Bionicle theme and medieval fantasy things, I wanted a Knights Templar helmet for a Bionicle. Unfortunately, I couldn’t find one on the internet, so I decided to make one. The piece is mainly just a cylinder with extruded faces (the detail around the eyes). It is completely possible to 3D print, unfortunately at the time I am writing this, i do not have an intact 3D print of the piece.
The piece obviously has a connector peg that is compatible with a Bionicle head piece, so that the character can actually wear it.
