Great concept and really wanted to love this. but there are rooms for improvement - As others have mentioned, there's print issues regarding the outer white shells. I've slowed down overhangs, played with nozzle temps, and changed filament to no avail. - Somewhat frustrating assembly process. Expect quite a bit of filing/sanding and gluing. - For me, the black side "ribs" we're getting stuck to the support (was wondering why it won't fit), so I had to use a knife and cut along the perforation then wiggle to separate.
