What ever you decide, just make sure it’s comfortable. Besides the shoes this is one of the most important parts. Unfortunately, jango has several layers with thick black leather vest. It can get really hot and really tight. So make sure you keep that in the back of your head.
Support wise mine works awesome. My MOW jetpack is very heavy. So just make sure yours is comfortable. Although yours should be fine if your 3-D printing the jetpack.
I started off as jaster mereel because I didn’t want to do a boba or din build. (that’s literally all you see at cons) After I 3-D printed everything I decided to go jango because there’s more source material and casuals can actually identify him. I’m very glad I made that choice. Should be a fun project for you.
