3d printed visors and ear protectors

Hi all, during my time in lockdown I've been keeping myself busy by making/printing face mask visors and ear protectors which seem to be very popular with hospitals, doctors surgeries and care homes etc just now, however the demand for these right now is making it very difficult to get these from suppliers.

I am hoping to raise £300 to help with the cost of buying supplys
Currently it costs:

£20 for a 1kg spool of filament which will make around 35-40 visors

£15 for 100 clear plastic sheets

Hopefully the money raised will help me to make around 300 face masks/visors and around 200 ear protectors
