101Hero Controller Mount

I took the top mount and made some adjustments for a sturdier fit.
1) Inside the notched end is 20mm to prevent the bracket from sliding
2) Two corners of the inner fill are curved so the bracket rotates in and locks.

Print two of these to securely mount the controller box to any of the towers.

Note: The bracket will only turn clockwise. For the bottom bracket, the fingers of the bracket should be facing 9 o'clock. For the top bracket, the fingers should be facing 3 o'clock.
