I've been at this for a few weeks now, modeling took a little while to get things right...had a few reprints to do which set me back, but now in a race against the end of the contest.  My Aliexpress delivery arrived and getting trying to get everything printed.

There's cheaper filament out there but I find I don't have to reprint as much with the good stuff.  Keene Village Plastics has been a solid brand for me, I mostly print ABS in the Voron and it doesn't smell as bad as some of the others I've tried.  It also adheres very well so long as I don't go past the edge of the heater matt.  I'm using black ABS for the black parts, dark grey for the modular bay as well as one of the buttons and the power port.  Love the color of the pearl sparkle copper Pet-G with the black and will be using it for the base.  Have used this color combo for my Head Amame headphones and a few other things I've made over the last few years.  In this case however it has a bit of the feel of an Atari 2600 color scheme.
