Mechanical Calculator Key Cap pulling tool. Lately, I've been tinkering with old antique / vintage Mechanical Calculators. These fascinating relics rely heavily on intricate gears, levers, and springs to perform their calculations. The most striking feature is the vast array of buttons on the keyboards. To maintain these machines, cleaning and servicing requires the removal of these buttons, a task that can be quite laborious and potentially hazardous if attempted with an unsuitable tool like a screwdriver. Thus, I created a tool designed specifically to pull Key Caps off in a smooth, linear motion, providing even support at their base. The tool works exceptionally well and is easily printable and assembled as demonstrated in my video. https://youtu.be/Tr2nGsmGur8 The design files include the original FreeCAD files, allowing anyone to modify the design for other applications if desired. I've been sharing my progress on YouTube. https://www.youtube.com/channel/UCtBGrxdGsbbyz9oZk8mKJbA/videos
