Still some work to do to improve this. Ideally the round grey piece would be a printed part in the official set. Maybe even fit an LED in there that changes colour. This is made from some old Hero Factory parts and also from a couple of Star Wars Buildable Figures sets from about 10 years ago. https://brickset.com/sets/75111-1/Darth-Vader https://brickset.com/sets/75117-1/Kylo-Ren Any suggestions on how this can be improved? submitted by /u/ForlanNdlovu [link] [comments]
