  Bottom opening 116 mm
  Fits a 220 x 220 x 250 mm bed (Ender 3 and similar) with room to spare

HOW TO PRINT THE ONE-PIECE VERSION
  1. Load cable-column_combined.stl
  2. Turn on vase mode (Cura: Spiralize Outer Contour / PrusaSlicer and Orca:
     Spiral vase / Bambu Studio: Spiral mode)
  3. Set SOLID BOTTOM LAYERS so the bulb holder prints solid before the
     spiral begins:
         solid bottom layers = holder height / layer height
         the holder is 10 mm tall, so at 0.2 mm layers that is 50
                                        at 0.3 mm layers that is 34
  4. Extrusion width 0.6 to 0.8 mm gives the best mix of glow and strength
  5. No supports. Vase mode cannot use them and this model does not need them.

SETTINGS THAT MATTER
  Layer height   0.2 mm for a fine even texture, 0.3 mm for a bolder rib
  Temperature    5 to 10 C above your normal, a single wall cools fast
  Cooling        100 percent
  Speed          30 to 40 mm/s, slower gives a visibly more even wall
  Filament       natural, white or a pale colour. Dark colours block the light.

SAFETY, PLEASE READ
  Use LED BULBS ONLY. PLA softens at about 60 C and an incandescent or
  halogen bulb will deform it. A 6 to 9 W LED is ample. Leave an air gap
  between bulb and wall. Use a proper E27 holder, flex and switch.

LICENCE
  Free for personal use. Print as many as you like, for yourself and as gifts.
  Please do not resell the file itself.
