Summary

The Robo3D has a lot of blue light, which is only for decoration. The visibility of the printed layer is poor. This clip has 8 white leds with a resistor of 390 Ohms in series (9volt power source). However, no PCB is required, only some simple soldering. It provides plenty of light and is fully self supporting. Direct light is shielded. By not modifying the printer itself, you are sure to keep the warranty.
