Printed the shade part with a perimeter of 2, and layer height of 0.2mm, took 10 hours on a felix 2.0.
The lamp running is 15w incandescent, so it wont melt anything, alternatively use an LED lamp.
The holder piece was made to mach my lamp, so it may need to be adjusted to suit your needs.
Holder Part was also printed with supports in its current position, alternatively it could be printed upside down, with supports under the arm parts.
