Simple quarter-sphere sconce

thingiverse

This is a straightforward two-part wall sconce that distributes light from a ring of LEDs positioned on the tray of the sconce as it's installed. Using a candle or even a votive on that tray isn't advisable, as the heat would likely damage the sphere; however, one possibility is to use the sphere as a mold to shape aluminum foil or the aluminum from a light-duty cooking tray and utilize it as a reflector. In this case, a votive candle might work just fine - except for the soot. I printed at .2 mm layer thickness, 1.2 mm top and bottom layers, as well as edge layers. Additionally, I rotated the 'stand' portion to print in the orientation that it would hang on the wall. Since I was looking for this item to be very light, I printed with a 5% infill. You may want to print at different sizes or with various materials. You could place an LED lamp within the quarter sphere and print it with a natural or translucent material; experimenting with diverse densities of infill will help you determine what works best for your needs. I've designed and added a LED half ring to fit on the tray. This setup should work adequately with a CR2032 battery and 9 x 5mm LEDs, though it's not perfect - it'll still function. Feel free to modify any or all of the elements to suit your requirements.
