Introducing a first prototyped hiding place for the constant voltage LED driver. Opqrstu3D designed it a bit large to ensure it would fit for sure and it did. Next, it’s time to redesign it as small as possible. That’s why you need a prototype; it shows all ‘wrongs’. I can see and measure new and smaller dimensions and apply them to the next prototype: a perfect hiding for the LED driver. Without 3D printing this prototyping would not be possible without thousands of Euro’s! Meet a siamese triplet and it’s hidden LED driver: ThreeBells.
