Waves4

This LED lamp uses the same basic geometry as  https://pinshape.com/items/45058-3d-printed-waves1 and https://pinshape.com/items/45119-3d-printed-waves2, but I changed open top container shape to one with a closed top that is suitable for an LED lamp. Then I added a base that accommodates an LED puck light. The lamp printed in just under 20 hours using a layer height of 0.200 mm and a print speed of 80 mm/sec.

The lamp accommodates either a battery operated or wall powered "puck" LED light. This blog page has links for all the wall powered parts needed and shows how to hook everything up: http://birkbinnard.com/blog/wall-powered-led-lights/. For battery powered puck lights just go to any large home improvement store or simply Google "LED puck light".
