Hands-free door opening handle to be mounted on vertical handle bars. There are two versions for 20mm, 30 mm and 35 mm diameter of the handle bar. We use it for the entrances at the department of mechanical engineering of the Bundeswehr University Munich. Put some rubber underneath to prevent the handle from turning. A cut up piece of old bike tube will work perfectly. Mount the two halfes with four M4x16 or M4x20 bolts and nuts and tighten with care. We printed some in Ultimaker ABS and some in Fillamentum ASA without support, as the are outdoors. PLA should also work. Settings were 20% gyroid infill, about 2 mm wall thickness. Due to the small contact area we had occasional issues with warping, which did not matter on the final part though. Building on a raft might be an option. There is also a version for regular door handles: https://www.thingiverse.com/thing:4463245 Happy printing! #stopcoronavirus
