PWM Motor Controller Case

A simple 3D printable case for a small motor controller using a 555 timer as the control logic. The PCB designed for this case was made by myself as a learning tool to see how 555 timers work and what can be done with them. The Github link for this is shown below. The circuit is designed to use a bipolar junction transistor, which is not ideal for this application. But it was used as it was the only transistor I had available at the time.
