HANDS FREE DOOR OPENER (Push & Pull)

grabcad

This is my gift to those who need a hands-free door opener on these unusual days. We are all affected by the COVID-19 situation, and measures to avoid contact with surfaces are highly encouraged. This situation is not ending anytime soon, so taking precautions when touching door knobs is always a good idea to stay safe. Suggested 3D printing Instructions: 1. Nozzle diameter = .42 2. Layer Height = .35mm 3. Perimeters = 34 4. Infill = 100% 5. Elephant Foot Compensation = .45 (inward) or as needed for your 3D printer and filament used 6. XY (horizontal) compensation = .05 (inward) or as needed for your 3D printer and filament used (the 3D model is a tight fit, so you will need it to slide and click successfully) Both pieces print in 3 hours approximately when printed in .35mm layer height. It is designed to print in PLA but other stronger materials could work too. Let me know if you have any questions. Happy Printing! And stay home! Also, it helps people with rheumatoid arthritis. Please print it and SHARE this product with your friends and loved ones, and get others protected from the Corona Virus with 3D printing! Design features: 1. EASY TO INSTALL. Just zip-it and click it (no screws, tools or zip-ties). 2. ONE SIZE FITS ALL. Can be installed on door knobs with diameters from 1.9 to 2.2 inches (48 to 55 mm). 3. Works for both PULL and PUSH side of the door. 4. REVERSIBLE for both LEFT and RIGHT swinging doors. 5. CURVED PROFILE for better grip. INSTALLATION INSTRUCTIONS: 1. Place the Knob Lever with the teeth facing the door. 2. Slide the Pull Opener into the levers. The upper lever always goes into the upper slot of the Pull Opener, and depending on your knob diameter, the bottom lever goes into the first or the subsequent slot of the Pull Opener (see third image). It should be as tight as possible for better grip and to prevent it from popping out of the knob when opening heavy doors. 3. Click the Pull Opener forward to lock it in place.
