Wrap a photo around a full cylinder for a lamp shade or night light, or lower the arc to make a curved standing panel. Set the diameter, the height and the arc from 30 up to 360 degrees; the inside stays a smooth cylinder and the photo sits on the outside.
You can engrave or raise a name or date that wraps with the photo, preview it in 3D, and download the STL, a print-ready 3MF or matching lids and bases with a hole for the LED. It is free with an account: register free, then build, preview and download, with a few downloads a day; Supporters download without a daily limit.
Choose it to fit your light: 70 to 90 mm suits a tea light or a small LED puck, and a wider shade suits a lamp fitting. Make the height about the same as the photo's proportions so faces are not stretched.
Only the arc. At 360 degrees the photo goes all the way round as a closed lamp shade; at 120 or 180 degrees you get a curved panel that stands on its own.
No. Printed upright, the curved wall supports itself.
Use 100 % infill, a 0.10 mm layer height (0.08 mm for the finest detail), a slow speed of about 30 to 40 mm/s and the fan at 100 %. Any gap in the infill lets light leak through unevenly. The full table is in the guide.
Yes. Engraved text glows brighter than the photo; raised text looks darker. Choose the position, size and style before you preview.
