Filament bulb desk stand

thingiverse

I stumbled upon this bulb at a local shop for almost nothing (40 cents), and out of curiosity, I decided to take one home. The light's nice color made me think it would be perfect for decoration, so why not create a simple holder? Created in SketchUp The bulb itself is 4W with a brightness of 300lm and an E27 type. My design is straightforward; I printed the holder using support touching the buildplate. After printing, I applied primer and golden acrylic paint to give it a slightly aged look. To secure the bulb, I inserted it with a slight tightness and used cyanoacrylate glue. The top screws are just for decoration and were screwed in after tapping threads. I used double-insulated wire and an inline switch. The wires were soldered directly to the bulb terminals, and everything is filled with rice (about 200 grams) to add stability. A tight-fitting cover from the bottom secures the holder in place using four self-tapping screws (2.5mm). Since I thought it would generate heat, I printed the holder from ABS. After two hours of use, however, it's still cold to the touch, so I'd recommend using PLA instead.
