Unless you've been living under a rock, you'll probably have noticed things are a little different at the moment. There is no arguing that Covid-19 is making us rethink our everyday activities.
But it's not all doom and gloom! Confined to their quarters, CAD modelers, architects and even total amateurs have taken up the design gauntlet, producing some really ingenious design solutions. From the practical to the whimsical. Many of these projects are being created free to download, open-source, models, which means that anyone can use or modify them.
Here are a few of our favorite designs:
Opening the door is something we haven't, in the past, given much thought to. But 100s and even 1000s of people use the same handles every day! For this reason, many people have endeavored to design a new method for opening doors without using your hands.

Largely these designs fit into 2 categories:
- Retrofit devices, that adapt traditional handles and allow them to be opened using your elbow or forearm.
- Foot grips, that allow you to pull the door with your feet.

Some great, free-to-download models include:
- Foot-operated door handle lever
- a range of different size hands-free door handle adapters
- Hands-free adapter for round, knob style handles
- Simple design
- Car door handle adapter
There are lots of also people busily designing 3D printable adapters for traditional style faucets (taps) that allow you to turn faucets on and off using your elbow or forearm.

It's not just door knobs that we come into contact with every day, from elevator buttons to touchscreens, every time we leave the house, we touch objects, potentially spreading viruses and bacteria.
One of the newest design concepts to emerge in the last few months are "no-touch devices". These ingenious gadgets aim to give peace of mind to anyone concerned about spreading viruses, without the need to wear gloves.

Designs vary greatly, but generally feature a hook, for things like door handles and draws, and some kind of poking device for touch screens and buttons. Typically they fit on the end of a key ring.
For added protection, they can be produced in some kind naturally, antibacterial material, such as brass or they can include space for antibacterial liquids.
These designs are in their infancy at the moment and currently have no scientific backing. However, as many of the models are open-source, there is huge potential for users to collaborate on this concept over time. Who knows, maybe in the future, we'll all carry one of these on our keyring?
Here are a few more examples, available to download free:
- The door claw
- The HandSaver
- Unusual clamp-style device
- The Cootie Crusher
- Modular no-touch device
- The Door Handler
- Retractable no-touch device
In many areas of the world, decontamination tunnels are being set up, to ensure the safety of members of the public when entering areas, such as large, outdoor markets or public transport stations.

The basic principle of the design is a tent-like tunnel structure with a set of hoses. As people walk through the tunnel they are sprayed with a light, chemical mist. This provides protection from the virus to both the individual and others in the surrounding area, for a short period of time.
Careful consideration must be given to the types of chemicals used to avoid irritation, allergic reactions or accidental poisoning. It's also important to not soak people, as this could cause other problems.
In all the tensions and uncertainty. It's important to remember to enjoy yourself as well. Some Covid-19 inspired designs are also emerging to help us remember to see the brighter side.
This Covid-19 inspired 3D printable dice set makes clever use of the unusual coronavirus shape.

This 3D printable Coronavirus is actually rather cute and would make an excellent desk ornament.
Or why not while your time in isolation away with this Covid-19 inspired, fidget spinner design?

Other entertaining -- although not scientifically tested -- designs include a Darth Vader style mask and a Minions face shield. Both design concepts would be great for children and help to take the fear away from the somewhat sinister-looking, medical masks currently available.
Then there are the frankly, outrageous designs.

A few people have taken to wearing large, home constructed "social distancing rings", like the husband and wife who created a social distancing ring from old tent pegs. For many, this is simply a way to raise public awareness on social distancing advice.
Companies stepping it up
It's not just individuals that are taking the lead. Amongst many others, both Lego and D'Addario (parent company of Evans Drumheads) are repurposing their manufacturing equipment to produce face shields.
Adapted from a GrabCAD design created by Alvaro Ugarte.
There are also a huge number of open-source face shield models available online and a huge number of individuals 3D printing face shields and other essential medical supplies, from their own homes.
