I decided on a simpler solution. An aluminum clip used as part of a lock for cabinets or desk drawers, sanded and painted the clip, the small and larger washers with flat black spray primer/paint. Drilled a hole on the console with a 3/32" drill bit and expanded the hole with a 3/16" drill bit to fit the #6-32 x 3/4 thumb screw.
The tricky part was connecting the wing nut and washer inside the console to the thumb screw. I used a piece of Scotch double sided tape wrapped around the wings of the wing nut so it would stick to my index and middle fingers. Also placed a piece of the double tape on the bottom part of the wing nut to hold the washer. It is hard to hold the wing nut and washer inside the console with limited space specially for anyone with fat fingers
I bought the clip from zoro.com, the thumb screw from Amazon, the washers, wing nuts, and paint from Lowe's. I hope this can help and will answer questions if needed.
