CrenelatedLamp3 & 4

These 2 LED lamps use the same basic geometry with one difference: the parameters for making the Loft surface that defines the outer shape are different. One set results in smooth interpolation between the 10 horizontal control curves that make the Loft surface; the other set results in straight line segments instead of interpolated curves.

There's more info about the crenollation design in the description of my other Crenellated uploads.

Each lamp printed in abut 20 1/2 hours using a print speed of 80 mm/sec and a layer height of 0.200 mm.

These lamps are designed to hold any one of several LED lights called "puck" lights. You can get these powered by either batteries of wall power. This blog page has links for wall powered lights that work well: http://birkbinnard.com/blog/wall-powered-led-lights/
