UPDATE V3: Corona Door opener Handsfree "Model Jena"

thingiverse

UPDATE V3_2020 04 08 This is Version 3 of the "Model Jena" There are minor modifications to the handle itself, mainly for added rigidity. However: In addition, you will find a sleeve that fits snugly onto the handle with a small gap. The reason for this design is so that you can easily remove and disinfect the area touched. If you use an antibacterial filament like COPPER3D PLACTIVE or similar, you'll need much less material. Someone may try printing the slave in TPU to improve haptics and chemical resistance, making it suitable for disinfection. I recommend using a 0.6 - 0.8mm nozzle due to printing time. When mounting the handle, try filling the gap with rubber or cloth to compensate for the difference in diameter between your existing door handle. XXXXXXXXXXXXXXXXXXXXXXXXX V01 There are numerous excellent door handle add-ons, snap-ons, and screw-ons available for download that allow you to open and close doors without using your hands. Hundreds of engineers, designers, and makers are working on a solution to reduce the spread of corona. The "Jena" model is one of them. My goal was to create an attachment that fits onto various standard door handles, is easy to mount and demount with 2-4 standard cable ties 5mm wide. It should easily fit onto a door handle with a round cross-section up to Ø24mm. If yours is smaller or has a different shape, simply wrap some fabric or rubber around it. Using a copper nano-composite antibacterial filament from COPPER3D, this handle will be "self-cleaning" in a certain way. However, it's still better than nothing. I'm currently in the testing phase with my local general practitioner. Please note that using this model is at your own risk.
