Hand's Free Door Opener: a Covid-19 Solution
Introduction: Hand's Free Door Opener: a Covid-19 Solution
This is a project me and my family designed as a solution to Covid-19. We have concluded that this is the best concept for a contactless door opener rather than a Covid Hook or Arm Opener. This is a very easy project to create and TinkerCad and will need little experience to make it. There are three different designs we built.
Features:
1. Easy to Build
2. Easy to Print
3. Easy to Use
4. Good Looks
This project was meant to help stop the virus, but not to completely kill of the virus. This was a family project to help my kids learn to use TinkerCad. My two sons are going into sixth and eighth grade. These designs are NOT the right dimensions and need to be bigger. If printing, please resize. The instructions are not showing the right size to print, they are just showing the size my family made in TinkerCad
Supplies
Overall, you will need an electronic device, a TinkerCad account, and some experience in TinkerCad.
(If you are printing this, you will of course need a 3D printer, and maybe some screws :)

Step 1: Our First Design
This design is not yet complete and may be completed sometime soon. It is a more complex design, and will require a lot of testing and redesigning until its perfect. The second picture shows two clamps. These clamps are supposed to go onto a straight, mitred door handle. It does require a highly durable string to allow the pedal to open the door. The pedal has several ridges on it, giving it a good grip on your shoe. The drill template is used to put the main body of the pedal to the door. The rail is meant to be something to limit the amount of travel the pedal can go, but we are still working on that. When this is complete, it should be ready to test. Please feel free to suggest ideas on this and try to come up with improved versions of this.
Step 2: Our Second Design
This is pretty much a complete product that needs to be tested. This is meant for doors that don't have locks, but still have handles, such as the ones in bathrooms at stores. 737
This idea/concept is a great idea because it can also be used for other reasons, such as opening the door with your hands full of items. This would be mounted to the door as the last picture shows. It will require three screws that will attach to the door. This concept has points at the edges to give grip to the rubber soles on your shoes.
Step 3: Our Third Design
This is pretty much a complete product that needs to be tested also. This is meant for doors that don't have locks, but still have handles, such as the ones in bathrooms at stores. This idea/concept is a great idea because it can also be used for other reasons, such as opening the door with your hands full of items. This would be mounted to the door as the last picture shows. It will also require three screws that will attach to the door. The reason this is different than the second design is because this doesn't have points, and also is mounted the opposite way than the other design. And also, the second one has way more shapes than this one.
Step 4: Second Design- Instructions
Start out by making a rectangle that is 49mm L, 23.5mm W, and 3mm H. Then make another rectangle that is 21mm L, 14mm W, and 3 mm H. Then add two wedges to each side of the second rectangle that are 14mm L, 14mm W, and 3mm H. This should align together as the picture shows above. Then, add 11 roofs that are 1.91mm L, 2mm W, and 2mm H and attach as shown above. Then, take a round roof and split in half. Then, resize the round roof to 49mm L, 3mm W, and 3mm H. Then attach to the main rectangle as shown in pictures above. Then, you're almost done. Make another rectangle that is 49mm L, 3mm W, and 14mm H. Also, put holes in the this rectangle that are 3mm by 3mm and equally spaced out from each other. Then group all objects together. Then you are done!
Step 5: Third Design- Instructions
Start out by making a rectangle that is 37mm L, 49mm W, and 3mm H. Then make another rectangle that is 61mm L, 2. 220
