Computer engineer Nick Pearson has turned his semi-detached home in Yorkshire into a factory with 22 3-D printers making 3,000 protective visors a week.
Nick, 25, swung into action with his girlfriend Lauren Rooney, 26, and the pair are offering their equipment free of charge to the NHS.
Then Nick’s employers – bookies William Hill - agreed he could do the project full-time instead of his job in software infrastructure.
And as the couple expanded their production the William Hill Foundation, headed up by Mirror columnist Robbie Savage, made a donation enabling them to purchase all the equipment needed.
Now the couple have 22 3-D printers – including eight on their kitchen table - in their semi in Churwell, Morley, West Yorkshire, producing sterile and eco-friendly visors for doctors, nurses, surgeons, pharmacists, GPs and care home staff.

Nick is helped by his key worker girlfriend Lauren, who works in food distribution. Lauren handles delivery logistics for their appropriately named NHSPPE project.
Nick said: "The response we've had is absolutely phenomenal in just a few weeks.
"I’m willing to put as many printers in my house as needed to get print times as low as possible, but with the quality still there. It's a serious production line.
‘William Hill have been very understanding and have given me a sabbatical to work on this full-time as well as making a fantastic donation.

‘My job at William Hill is important, but nothing is more important than helping out in this pandemic.
‘The William Hill Foundation donation paid for eight printers, 150 kilos of PLA plastic and 10,000 sheets of PVC to help make many, many visors.
"The more money we raise, the more printers we can buy and the more life-saving visors we can produce."
Deliveries have already gone out to hospitals, surgeries, pharmacies, care homes in Leeds and further afield.
The couple have set up a fundraising page at https://NHSPPE.net to raise money for production.

Nick added: "It’s close to me, I’ve got a lot of family who are classed as vulnerable. I just want to help people stay safe, to do something that can help.
“It’s really important to look at your skills, what you’re good at, and work out how you can help. Take a look around - are you good at sewing? Can you make aprons?
“There are a lot of groups that need help on Facebook with all kinds of things. It’s time for everybody to pull together.”
They have now expanded the team for round the clock production with electrician Daryl Abbott, 38, of Beeston, furloughed travel agent Danielle Finn, 28, from Farsley, and printer Richard Robinson, 29, from Otley, also on the volunteer rota.
