Light-Ring for Dremel 220 Workstation

thingiverse

This is intended for Dremel 220 Workstation. I needed something to light up the work plane while drilling PCBs. Shadows are very boring when you're trying to meet the holes! So I created this simple light-ring, made up by 6 LEDs and powered by 12V power supply. ISTRUCTIONS:<ol> <li>Weld LEDs together using holder ring.stl as guide. I used 6 flat-cap LEDs, but you can use any kind of 5 mm LED. Don't forget limiting resistors!</li> <li>Put it into holder outer.stl. Push firmly.</li> <li>After welding power chord, close everything using holder cap.stl</li>. Use just a little bit of glue to avoid it accidentally open up during Dremel operation. </ol> Simple LEDs connection scheme is included for your convenience. CAUTION: do not permanently fix the light-ring to the workstation. The light-ring must be movable, since it tightly surrounds the locknut of the workstation (the big black nut). The light-ring must be only placed after assembling Dremel into the workstation. In addition, you can try to use the light-ring to tighten the locknut itself. After, to fix light-ring, I used simple paper-tape (see pictures), but one can try to use neodymium magnets in order to create something nicer.
