Crystal Lamp Cover

this model is hallow by design, done in fusion 360 . 

this design also comes with a Base and was used to sit on a cheap lamp i found in someones garbage , so i do not know the manufacture this lamp has an inline switch that i found and designed it with the standard lamp fixture. 

i printed this in a rainbow glow fill 4 perimeters
no infill needed would not recommend infill as it will cause patterns could do well with shells 

was designed so no supports needed.
