here is a simple mod - rocket flame light dome
not the cheapest option from shape ways, but that is due to the resin printing process

Simply swap it out with your regular light dome for the flame dome and put in a coloured led (red, orange or yellow) or use some glass paint (on the inside or outside) to achieve a cool flame effect.
The inside is hollowed out with a tapered starburst effect to aid in spreading the light and each outer side is different with a random flame effect.
