The cutting tools (dies) for cutting flat sheets like this can be made in literally one day by the type of factories that Apple works with (less if you're in a real hurry). I visited a cardboard packaging factory near Shenzhen before; They use a combination of a CNC router to cut out slots in the die base plate and a CNC folding machine to pre-fold the cutting angles into the cutting blades. Smaller hole / lozenge shape cutters are sourced in as pre-fabricated components. The design is very smart from a manufacturability point of view, I expect we will see other factories making similar face shields in the 100s of millions shortly. Which is great... One of our local supermarkets is already using similar face shields for their customer-facing staff.
