I have an Ender 3 3D printer. It takes melted plastic and prints it layer by layer to create an object. To learn more about 3D printers here is a link with more information.
I have done some modifications and upgrades to it as time has gone by. I first added a CR touch that probes the print bed to measure its flatness. When printing, it is important that the print bed is as flat and level as possible. I also upgraded the control board to Creality’s V4.2.7, which had a port for the CR touch and quieter stepper drivers. This greatly reduced the noise. I upgraded the Bowden tube, which carries the plastic to where it will get melted, to one with a higher melting point.

I had to replace a couple of broken parts on it after a while. The plastic extruder feeder drive arm broke. I replaced it with an aluminum one. The belt tensions weren’t working after a while and were difficult to calibrate so I upgraded them. I could have printed both parts but since I needed them to print I had to buy them instead. If I had another printer I could have printed the spare parts. One of the blades on the hot-end fan broke so I also replaced the fan.
Creatiliy makers of Ender 3 only tin the wires to the control board. Over time the wires get loose after compression. The electricity can creep and heat up the screw terminal which can cause a fire. I put ferrules on all the wires that protect them and replaced the control board with BIGTREETECH SKR Mini E3 V3.0. This video explains the problem very well as well as how to ferrule the wires. I also got an enclosure to be a little more fire-safe and to keep a more consistent temperature.
