I am struggling with this part of the project - modifying code that connects my ESP32 to my iOS device. I think I need to go back to basics and handle each feature of the code by breaking them down to the bare, essential parts and trying to code those into the sketch. This is by far the longest part of this project but I'm willing to learn. 

I really need to buy a 3D printer, outsourcing it is immensely expensive. At least I'll be able to work on the code until I can buy a printer.
