Creting a New Method for Manufacturing Concertina Buttons

Basic Explaination

At my old Job at Carroll Concertinas, there was this very difficult part on one of the buttons on the instrument that required using a lathe and a drill press. It took way too much time and there needed to be several of these parts Using my knowledge of 3D printers, I thought of a better way to make this part using 3D printers. I started my research into it by getting the original engineering drawing and recreating the part in Fusion360 and creating an updated engineering drawing (shown below). I created a new engineering drawing and exported the file to do structural modeling on it. I simulated several different force loads on the button. I found that ABS is too weak for this application, especially regarding the sharp points. I optimized it as best as I can and decided to use a resin 3D printer as I have more experience, and they can produce much stronger parts. I found a very strong resin which in the past I used to 3D print pressure vessels for my pneumatic baseball bat. This project is still ongoing and hopefully I will have it fully implemented by the end of the year.
