Prusa I3 Mk2
what did you use for the bulb?
For the top bulb I used a soda bottle preform. It has a little cotton stuffing inside to disperse the light.
may i ask what type soda bottle? i don't think i've ever seen a soda bottle that small.
Its called a "soda bottle preform". Do a google search for it you will see what I mean. They usually only sell them in packs but they are pretty cheap.
