For the 3mm version you will need 8 M3x12 and the 5mm 8 M3x14.

The top front brace was two versions, with built in standoffs and without (will need to print 2 standoffs and brace).

Another option is to use the "cut" version, which removes one portion in the center, or the "full" version, which uses more plastic.
