Aspiring engineer designs PPE visor-mounted fan
26 June 2020
Toby Weymouth, aspiring engineer and marketing assistant at sensor experts PLUS Automation has designed a PPE visor mounted cooling fan to make Coronavirus protection easier to wear in the summer.
The A-level Design & Technology student and Arkwirght Engineering Scholar worked to design and refine a fan housing which hobbyists could manufacture for themselves and their local community on a 3D printer. He also wanted to produce a high-quality, quiet solution which was comfortable to wear.
The design uses a 3D-printed housing to contain a small, light, quiet fan, which clips onto any visor and is powered by a USB phone battery pack, connected using a 1.5m cable. The battery pack can be kept in the user’s pocket, which removes the weight of the fan on the head. In addition to this as many people already own these USB battery packs, it enabled the cost to make a fan to be kept to around £5 each, on the assumption that the user would provide the battery.
Another key benefit is the reduction in waste because in future the USB portable battery pack also be used for many years, recharging phones etc. A typical small battery pack will run the fan for half a day, whilst a larger pack is capable of running the fan for an entire working day. The USB battery packs can instantly be swapped and they are recharged using phone chargers, laptops, or increasingly USB plugs.
With the help of Midland’s based 3D printing experts Central Scanning and the American 3D printer manufacturer Makerbot, the fan housing’s design has been optimised so that it can be made on home and hobbyist 3D printers. Toby has provided a variety of designs for download at the website www.CoolingFans.co.uk.
Detailed instructions of how to mount the fan, make the cable and where to buy all of the components, even the tools are also listed at Parts.CoolingFans.co.uk and electronic component supplier, CPC, is offering specially reduced prices.
If you can help make fans for nurses, carers and other key-workers, please check out the website – If you lack the practical skills, you can donate to buy parts for others to assembly – A fan, housing, and cable costs around £5 and hopefully will make wearing a PPE visor a lot more pleasant - www.JustGiving.com/crowdfunding/CoolingFans
