The lamp is a two part design, with a top and a base, so you have access to the bulb by removing the top. The redesign work took about 4 hours. I printed the top on myAirwolf3D v5.5 which took 3:41. I couldn't print the base on the Airwolf because it only has an effective build height of 100mm (4in) and the base is 195mm (6.7in) tall. So I printed that on my modified Prusa i3 which has an effective build height of 255mm (10in) Printing the base took 15:32.
