There's this program I use that lets you fine tune it pretty well. you can change the design piece by piece, change materials or colors, and even lay out the logic!
It's called: StarMade
(seriously tho, SMedit used to work, but I think is broken right now. There's also
SMBEdit but it uses command lines so if you're like me and Jon snow and " know nothing" about that, then the game itself is probably your best bet)
