This is a modified version of this thing: https://pinshape.com/items/14716-3d-printed-2-tabl...

It is basically the same part as the ribbed lamp but without the internal surfaces and an integrated base. By making the base part of the lamp itself the need for a second part is eliminated and the whole thing prints faster and easier. I also changed the shape of the ribs a bit; they are wider and a bit thinner. The 2 photos show the lamp in daylight with it's light off and in a dark closet with the light on.

The light source is a standard 68mm/2.75" diameter LED "puck" light that is powered by 3 AAA batteries. I bought 3 of these lights at Lowes for $9.98 batteries included.

Here is a link to the puck light:
