Modified the original design to be used with 2mm acrylic sheet and added a strap adapter for non-elastic band. I used PLA (The parts are thin enough to be flexible).
0.2mm layer height, no rafts or brim, supports only at the ends of the head mount and the end of the strap adapter (strap-adapter_02 without supports).
I used white PLA from Das Filament.
The author remixed this model.
