This will weaken the leg and could loose its elasticity, proposed solution is to open a square to fit reset button and make the leg little wider.
It's easy enough to cut off part of the leg to clear the button.
Nice mount, but it doesn't fit when you have lcd adapter connected otherwise it will touch the reset button.

Had a bit of trouble keeping the ends down as the head would come across and peel it up but then made a small bridge across the ends now it works.Thanks
thanks for the .dwg! the one you derived from was a bit too wide to grab my ramps board.
Why waste your printbed fan control for cooling your RAMPS board? Just wire the fan to 12vdc!
Can you explain more? Maybe a pic.
Right beside your X-Axis Pololu chip just to the left is an innocent looking 2 pin connector, thats where your fan plugs in.to cool your chips. If it doesn't turn on, it could be because it's not enabled in your firmware. It's referred to as Pin 23 in Sprinter and Marlin. In the firmware you can also modify it's operation to run when it prints or keep it constantly running.

If you look at the pictures for Thing 30331, you can briefly see where fan plugs in.
