The Simple Door Opener: A Versatile Tool for Everyday Use. Proven to withstand heavy use, this device can effortlessly open most doors without needing to touch the handle. Its robust design has been thoroughly tested and meets all expectations. Not only does it excel at opening doors, but it also serves as a reliable tool for switching lights on and off or pressing lift buttons with ease. A thoughtful feature allows users to attach a keychain to the device through a strategically placed hole. For those who prefer an alternative method of attachment, a second version of the STL file is available, enabling users to easily hook the device onto a badge holder using a longer hole. This design makes it simple to print multiple units at once on standard bed printers, with a maximum capacity of 12 devices per print job. However, some users have reported issues with the second layer dropping onto the printer bed. To resolve this problem, two solutions are available: either slightly reduce the bottom thickness of the STL file by 0.2mm or add support to prevent the issue altogether.
