In order to ensure precision in dimensions, I made every effort with the base measurements, which are relatively precise. However, the nobs and LED lights have a rougher appearance but still maintain close proximity to the intended size. The buttons have slightly off curves, while their width is correct. For rendering purposes, set the "blue plastic" component as translucent and the "light" component to an emissive material for a glowing effect.
