MR. BEE BUILD GUIDE
To get a bunch of smaller casings
from the kit, you'll need to break
one large acrylic piece.
But please, be super careful when
doing this to make sure you don't
damage the parts you need.
After breaking it, you'll end up with three separate pieces
of acrylic casings. If you find there's too much excess acrylic
in the holes of the casings, just gently push it out.
