cults3d

Moulding of 3 coffee filters N°4 with white glue between the mould_inf and the mould_sup: place the first filter (seam down) in the lower mould, glue a small piece of curved cloth on the filter in the nose area. make a small bead of glue inside the filter along the crest line of the mould_inf Place the second glass against the first one, insert the mould_sup, compress the bottom and the sides well before repeating the operation with the last filter, cut out the excess paper and extract the pieces from the moulds. After drying, drill the fixing holes using clip_1 as a template before crimping the rubber bands between clip_1 and clip_2. Elastics can be more simply stapled to the sides of the mask. https://www.youtube.com/watch?v=f_ABlxWD-1s https://dailycoffeenews.com/2020/04/13/coffee-filter-giant-melitta-making-millions-of-face-masks/
