Geeetech i3 pro b e27 lamp holder

thingiverse

I built this because I was fed up with relying on my phone's flashlight to inspect print quality, even with room lights on. Using only black PLA makes the situation worse. I repurposed a dying 3-led, 3-watt E27 lamp that needed its driver replaced, utilizing the unused stepper motor driver slot for the second extruder to power the LED board directly from a 12-volt source. After printing, I noticed that the threaded insert was slightly undersized. To fix this, I removed the metal cover and reduced the plastic screw's size, ensuring it fit snugly now. **Print Settings** * **Printer**: Geeetech i3 Pro B * **Supports**: No * **Infill**: 15-20 percent * **Notes**: To prevent support structures entirely, place the object on the bed with the E27 holder's back flat and its base pointing up. Using Cura, I added five contours of brim for improved adhesion.
