Andon (行灯) - traditional Japanese lamp

thingiverse

A lamp styled like a traditional japanese andon (行灯). I used this light bulb socket but I provided the .stp file for the main post if you want to modify it for a different one. More picts and info on my blog. The lamp measures 285mm X 200mm x 200mm but is printable on a typical 200mm x 200mm bed. Just rotate the long vertical members 45° to fit along a diagonal. Print 2x base.stl, 4x column.stl, 22x spar.stl, 1x maincolumn.stl or make your own, 2x key.stl to connect it, and optionally 2x frame.stl for mounting a picture or optically diffusive fabric. I used vellum paper in an inkjet printer, after lightening and desaturating the image slightly and being careful not to smudge the print while it dried. The columns connect to the base by tapered dovetail joints, and the spars are inserted into slots but are non-structural. Glue is optional, but recommended for attaching the main column to the base via the key joint. Use ABS or PETG for key.stl and the main post to avoid softening in the bulb's heat. I'd recommend not leaving it on and unattended for long periods of time either way. Mine just happens to be a few feet from a fire extinguisher. Print Settings Printer: Monoprice Maker Select (V1) Rafts: No Supports: No Notes: I scaled mine down to 96% in the slicer and used the extra space for a brim to prevent warping. It also provides margin against skipped steps in case the printer's endstops aren't precisely located and an axis bottoms out. Be careful not to pry the brim away from the rest of the part as it will likely peel the first layer with it. Use multiple perimeters for strength. Infill is negligible except for creating the top layers for each base.stl Post-Printing Left-to-right: As printed, sanded, stained, and coated in varnish. If you use wood-filament, sanding and staining will bring out a more wood-esque surface finish. I sanded to 800 grit without removing so much material that the layer striations disappear- the right amount of sanding makes them look similar to wooden grain. Additionally, you may want to refine the fit between the joints to minimize gaps on the exterior. They have a ±.15mm tolerance but my printer still resulted in more of a press-fit for the main columns, mostly because of the radius at the base of the dovetail joints.
