Dodecahedron Lamp - After AK Eric

thingiverse

Here's a version of AK Eric's dodecahedron made into a lamp that adds a two-piece base, which can hold a light socket inside the dodecahedron. This lamp comes with various grill designs to choose from and uses printed clips to hold the pieces together instead of zip ties. This project involves mains wiring, so be aware that it requires careful handling. If you're not confident in your ability to do this safely, get help from someone who is experienced or take a class. You are responsible for ensuring the safety of anyone using something you build. To make this lamp safely, follow these instructions carefully and consult with an expert if necessary. Do not use incandescent lightbulbs as they may melt the plastic and create a fire hazard. Use LED or CFL bulbs instead, and write it on the bottom of the lamp to avoid confusion for future owners. You'll need the following parts: * A small/mini-sized CFL or LED lightbulb that fits through the hole in the pentagon piece. * A 3/8-inch (9.5mm) diameter all-thread nipple, approximately 1 inch (25mm) long. * 1 to 2 nuts for securing the threaded nipple. * A low-profile light bulb socket that threads onto the 3/8-inch threaded nipple. * Lamp cord, however long you want it to be. I used 8 feet (3m) since shorter cords are usually too short. * A plug for the lamp cord and an inline switch. To complete this project, use the following tools: * A Dremel or rotary tool * Wire strippers * A screwdriver Instructions: 1. Print 12x of "pentagon piece V2.STL." If making it a lamp, choose an infill pattern that won't show when the light is on. 2. Print 11x of "twisted grill v2.STL" or your preferred design. Place the object in your slicer, taking note of how the part's corners are tapered to match the pentagon piece. 3. Decide whether you want the shiny, bed-side finish to face outward or the rough, 3D printed texture of the top. I prefer the rough texture better, so I printed it upside down with the taper spreading outward. A concentric infill works well with the "twisted grill v2.STL" design. 4. Glue, screw, or friction weld (with straightened filament in a dremel) the corners of the 12 grill pieces to the 12 pentagon pieces. Be sure not to cover up the little square slots for the clips. To complete the assembly: 1. Wire the light socket and secure it to the threaded nipple. 2. Thread the "base upper" onto the wire, followed by a nut. 3. Tighten everything together carefully. 4. Glue or friction weld the "base bottom" to the "base top." It may take some pressure due to the wire in the slot trying to push the pieces apart. 5. Snap "base upper" into the last pentagon piece with no grill, being gentle if using PLA. Insert the lightbulb and clip it to the dodecahedron's remaining pentagon piece using the printed clips.
