Leafy Lampshade - Banana leaf inspired

thingiverse

This is a fast and basic lampshade inspired by banana leaves. Banana leaf-like design elements are single-layer (0.25mm) thick so will require precise printer adjustment! The center part has a 30mm hole to fit a B22 batten (not sure about E27 - sorry, I don't have one to try it on). The center has slots for fitting either 5, 7 or 9 leaves at regular spacing around the perimeter. How to make it: - Print one central part, preferably without extra shells as holes will be too small otherwise, and use 15% infill (or whatever you prefer) - Print 5, 7 or 9 leaves. Three will work also - just use every third hole of the top row - Carefully fit base of leaf stem into appropriate hole in central part - Attach to light fixture NOTE: Suitable for CFL or LED lamps only! You may have issues getting the leaf stem bases to fit in holes - either file/sand them slightly or file out the hole with a square needle file (3mm or smaller). Ideally, stems should press in snugly until the flange touches the base part. Leaves print flat but will sag under their own weight. The amount of sag depends on your specific filament. I made two lampshades while developing this design, one used translucent green PLA for leaves, and the other used aluminum, copper, and brass metal-fill (see pics). Green PLA sagged a lot; metal-fill didn't sag as much. I may adjust this design depending on how my shades fare. I'm happy with them so far but probably think of improvements later on... Print Settings Printer: Duinotech TL4090 Rafts: No Supports: No Resolution: Layer height 0.25mm Infill: 15% Notes: I printed the central part at 0.25mm layer height, 0.3mm path width, without extra shells. Leaves were 0.25mm layer height and 0.4mm path width, with one extra shell. Printing time was 75 minutes for center and nine minutes each for leaves
