PlaySeat Challenge Dual Bass Shakers (Foldable)

I couldn't find a good design to mount some regular bass shakers on the PlaySeat Challenge so I created my own.

This will not affect the portability of the PlaySeat Challenge, nor the comfort and easiness to get in/out to/from the chair.

I used M4x30 to mount the base + clamp on the frame, and I guess any M4 will do to fit the bass shaker on the base. Regular M4 nuts should fit into the hexagon-holes.

I hope you will like it!
