This is a simple symmetric bracket that mounts on the RAMPS shield. No screws required to attach the bracket to the board. Fits 40 mm fan with bolt spacing 35 mm (1.4") outside to outside. Three improvements have been added. Nut trap on the inside, small skirt to channel air, and increased depth to not interfere the stepper wires,


Use any RAMPS mounts (not enclosments) to mount your board to the fram. Then attach this simple device and wire your fan into D9. Use Gcode M106/107 to turn fan off and on.

Fixed my skipping stepper issue as soon as I started using it. Just be careful not to press the reset button...lost a small print due to this.

I tried printing several cases and different designs, but I always keep coming back to this one.

Very nice design. I printed it and mounted my fan in about an hour. It cools the FETs for my extruder and printbed heater circuits very nicely, solving my problem. I like the way that you can slide it along the Ramps pcb anywhere you want it (except for where the reset button lives). Good job on the design!

And if I need to service my ramps board, it will snap off very easily.

I hardwired the fan to my +12V source directly. Runs whenever the printer is powered up...doesn't bother me. Might try the smarter approach if I feel frisky later.

Nice mount, but it doesn't fit when you have lcd adapter connected otherwise it will touch the reset button.

It's easy enough to cut off part of the leg to clear the button.

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.

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 http://in.toin.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.

Thank you for taking the time to write this. I will try this soon!
