3D snowflake STLs

Pattywac suggested I modify my laser cut thingiverse.com/thing:5008 so that it can be entered in his MakerBot vs the Holidays challenge. So here are the STL files. Parts A & B are 111 x 111 x 3 mm; part Cs is 111 x 114 x 3 mm. I understand there may be an issue with the print dimensions; please see comments below.
