Polyhedra Lampshade

prusaprinters

I needed a new lampshade for my bedroom because the old one sucked big time, so I made this one based on a particular polyhedron called "icosidodecahedron" (more about it on wikipedia : https://en.wikipedia.org/wiki/Icosidodecahedron).The lamp is made of pentagon frames screwed together with M3 screws, and various lids easily clipped on those frames for easy customization.The whole thing is 35cm large and weights less than 400g.I also provided some patterns you can print and glue on the pentagons to customize it more to your liking. If you want to add these on the pentagon lids, you can just use some glue or double sided tape.Parts needed for a fully enclosed shade :12x pentagon frames11x pentagon lids (flat or pointed)20x triangle lids1x e27 shade ring25x M3X4 screws5x M3x8 screwsI personally chose to print only 15 triangle lids and let the 5 top triangles open to let the light draw a nice star shaped pattern on the ceiling.Update 07/12/2020 : Added a "pointy" pentagon to give the shade an even more rounded look. It's to be printed flat and then folded into shape. Quick tip : folds better when still warm. If the print has already cooled down, you can just heat up the bed and let it warm for a couple of minutes.Print SettingsPrinter Brand:CrealityPrinter: Ender 3 ProRafts:NoSupports: YesResolution:0.2Infill: 20%Filament: Sunlu PLA Black and White Notes:I printed everything with PLA+ from Sunlu in black and white, with supports and brims to avoid warping on the frames (but they are minimal).For better results when printing the pentagon and triangle lids, you need to have a perfectly leveled bed.  Category: Decor
