Retractable Pocket Door Hook against Covid-19

thingiverse

There's now 2 versions included, one that matches the pictures and a 120mm version which is 20mm longer. The hook retracts 10mm further into the case in the 120mm version, so when you use it to push buttons, the possibly contaminated front part of the hook doesn't touch your pocket. You only need to print 3 parts, not 6 parts. This innovation wasn't exactly a remix of this very useful thing "SwitchHook Door Tool for COVID-19" but it was inspired by it. Check out that thing too if you came here for the hygiene. During times of a pandemic, it's helpful not to touch door handles because viruses love door handles. To flatten the curve, you should avoid touching door handles when possible. There are already many designs of hygienic hooks on Thingiverse, some of which I have tried and used. The problem I had with these is that I have to disinfect them every time after use. Because when I put them into my pocket, I can't easily avoid touching the parts of the hook which came into contact with the door handle and possibly collected some viruses and bacteria on its surface. That's why I designed this retractable hook, which retracts into a box after use, with the surface that touched the door inside the box. This tool is designed to be easy to print (without supports), even on badly calibrated printers, and easy to assemble. No screws or other extra material needed. It uses a simple snap fit mechanism to hold together the case. To retract the hook, you have to hold the case with its opening facing up and push the button on the side of the case. To unretract the hook, you have to hold the case with its opening facing down and push the button. Dimensions are a little more than 100cm x 60cm, fitting into typical pockets. It can be used to grab door handles up to about 35mm thickness. I didn't test it much yet, but I got the impression that it's not easy to break during typical use (which is pulling down a door handle and opening the door). If it does break, I may design an updated version which is more robust. A Fusion360 file is included if you wish to adapt the model to your needs or remix it. You must not sell this design for more than 5€ unless I gave you permission. Selling it for less than 5€ is permitted.
