Magnetic no touch door opener
thingiverse
I designed this handle inspired by rjelbert's "no touch" tool, but completely reworked the models to fit a 7-8mm diameter and 3mm thick magnet in the handle and back of the base. This keeps it shut when not in use, reducing the chances of accidentally touching the handle portion if put in a pocket. I designed holes for M4 screws as clearance fits, but you can modify them with the STP's if needed. I recommend printing the middle handle with extra perimeters for strength. Printing with PLA gave me a smooth surface that slid well against itself when tightened and loosened to get the right resistance. If your printer handles overhangs well, you might be able to print without support. Only the countersinks on the front and back cases need support. I used two magnets like these: each assembly needs two total magnets. I ordered them from Amazon - https://www.amazon.com/DIYMAG-Refrigerator-Magnets-Premium-Brushed/dp/B07B3SDRCP. Note: The uploaded photos have slightly different screws because that's what I had on hand during quarantine! I redesigned for M4's since they are more universally accepted.
