Harwin is 3D printing masks for local hospitals, healthcare settings, doctors and pharmacists close by to its Portsmouth UK HQ. Due to popular demand for suitable mask designs from the maker and printing community, Harwin is making the design available to anyone that wants to print on their own equipment.
This design has been optimized to be printed quickly, thus maximizing the number of masks that can be produced. A simplified version of existing designs, the mask band has four pegs to clip onto a plastic sheet and is a third of the thickness of some other designs. The visor is a clear acetate – the sort used for overhead projector sheets – and can be bought from multiple online retailers.
