Swing Arm Mount For 120mmx120mmx25mm CPU Fans

I created this swing arm mount for the fan I use to ventilate fumes from my 3D printer. The fan is on a swing arm, so it can easily swing towards my window to extract fumes outside and then swings away when I am done. You will need hardware to assemble this together.
Hardware I used:

• 2 M6-1.00 x 40mm screws and 2 M6-1.00 nuts
•  2 M6-1.00 × 55mm and 2 M6-1.00 nuts
• 2 608 2RS Bearings, 2 5/16"-18 × 2.25" bolt, and 2 5/16"-18 nut
• 4 #6 × 1" Drywall Screw, #2 Phillips Bugle Head, Coarse Thread
