This is a more accurate support to wear disk on the back, according to movie https://propstore.com/product/tron-legacy-2010/identity-disk/
perfectly fits with GraeMcNuggets's V2 Identity disk
Glue 8x2 or 8x3 magnets inside the support, to match polarities of the magnets on the disk
3 designs :

• flat, to fix on your suit with flange
• 3 degrees angle, to fix on your suit with flange
• flat, to fix with straps
  And 2 versions, with or without Kevin Flynn's etching (this design by Creator1326 https://www.therpf.com/forums/threads/kevin-flynn-build-and-lessons-learned.233287/ )

With flange, I plan to use 'Ikea' screws that are dia 6.1x16.7 mm
You don't need the 5 screws, but you can choose where to put them
