Lamp 1, 2, & 3 as originally posted to Thingiverse.  I made these as a Christmas present to my grandmother with Lamp 3 created later using Meshmixer.

Fits a LED light with a diameter less than or equal to 30 mm.  (I used an "Everlasting Glow Water Lights Submersible Color Changing LED Light" from Bed Bath and Beyond).

Lamp 3 was successfully printed at 50% scale.

Included the original Inventor .IPT files.
