RC Body Wheel arc cutter

Wheel arc cutter for RC bodyshell. Does need some hardware as below.

Important to place the magnets in the correct orientation so they attract to each other. 

I fastened the magnets with superglue. Also there is STL of 5 X 8 x 2,5 bearing in the files if you want to use that instead.

• 4pcs 8 X 3mm magnets
• 14pcs 6 X 3mm magnets
• 2pcs 4 X 3 magnets
• 4pcs M6 carbon steel washer
• 1pcs M2,5 Heat insert
• 1pcs M2,5 X 5mm screw
• 2pcs M4 nut
• 1pcs M3 Heat Insert
• 1pcs M3 X 10mm screw
• 2pcs 5 X 8 X 2,5mm bearing
• 5mm shaft 33-35mm long 
• 3 xato knife blades

This is for the full assembly.
