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