This mount is intended for use with the Mamba Monster X Esc without its upper case. It won't fit older versions! It allowes you to mount your own 30mm fan. (hole to hole space 23.9mm)
The mount is symmetric, so you can choose if you like to have the switch in the upper left or lower right position. For switch position upper right, lower left and front or back look at the versions a and c in my shop.
Hole to hole distance for mounting in the chassis is 52 mm.
May contain small parts. Don't let children get it, danger of suffacation!
