This lamp is easy to print, easy to assemble and easy to operate. You turn it off and on by simply pressing down on the top. It is designed to use the IKEA Kapplake LED, which is available for around $5, which makes it quite affordable as well.
Print without supports, I recommend a brim for the spiral top. I would use >40% infill in the base to avoid too much light bleeding through.
Have fun Printing and enjoy!
