There are several very good door handle add-ons, snap-ons and screw-ons available for download regarding opening and closing a door without using your hand. Hundreds of engineers, designers and makers are seeking for a good solution for the reduction of spreading corona these days. The model Jena is one of them.
My aim was to develop an attachment which fits onto several different standard door handles, is easy to mount and demount by using 2-4 standard cable ties 5mm width. It should easily fit onto a door handle with round cross-section Ø 24mm max. If yours is smaller or has another shape, then simply wrap some fabric or rubber between.
By using a copper nano-composite antibacterial filament from COPPER3D, this handle should be self - cleaning in a certain way. However it is definitely better than nothing.
At the moment I am in the test stage with my local general practitioner.
Using this model is in every manner on your own risk.
