Modular Moire Refracting Vase Lampshade v1.3

prusaprinters

<p>Inspired by moire patterns and fascinated by vase mode prints, I have been exploring multiple ideas to design a modular and adjustable lampshade, which would allow to create an interesting play of light refraction, possibly also some moire effects, and offer easy tuning possibilities for the visual appearance. At the same time, I was looking for simplicity (both printing and assembly) and a bit of extensibility. The result may not be a final look, but a start of bigger journey, as there are countless various patterns, that could make the light perform magical tricks when combined together.</p> <p>This lampshade is IKEA Hemma compatible and consists of 3 parts which stack onto each other and are secured by the bulb socket fixture ring after finding the desired arrangement. As long as the retaining ring is not tightened firmly, you can turn individual parts independently and exlore the combinations.</p> <p>You can let the lightbulb to shine as point-ish light source to one part of the room, while the rest gets more diffused light, with a possibility of seeing some interesting refractions and moire patterns from there. You can also keep it evenly "closed" and enjoy a bit softened light, or have fun with adjusting it and looking at the light play. Some positions throw the lamp out of weight balance, but that could be solved e.g. by some adjustable counter-weights.</p> <h3>Print instructions</h3><p>Printing:<br/> Designed for transparent materials, PETG recommended.<br/> use vase mode (spiralize outer countour)<br/> line width 0.5 mm on .4 mm nozzle worked fine for me.<br/> Layer height 0.3 mm for fast print times and probably better light transmission &amp; appearance. Larger height with wider nozzles is possible too of course.<br/> Solid bottom is required, your slicer has to support the combination.</p> <p>Assembly:<br/> No tools needed. Just stack the parts on the lightbulb socket shell, beginning with the largest one and ending with the smallest. Then thighten the ring.<br/> Use only LED bulbs, matte or filament-ones. Preferrably lower wattage/ light output as well, as you will want to look into the light :)<br/> Although the design includes vent holes to keep some airflow (as even LED bulbs produce some heat), the tungsten or halogen hot running bulbs would melt or deform the plastic anyway.<br/> Orientating the openings to the same side allow for easier lightbulb installation.</p>
