Step 10Secure the Fan Gear With Two Screws
iImage Information

Once you believe you have the proper mesh, you will want to drill two more holes in the top of the pinwheel shaft by the location where you previously melted wires for the LED. This is in order to make holes for two screws which will be used to hold the main gear attached to the fan in place while the device is in operation. You can determine the best spot to make these holes by holding the fan gear in place and using a permanent marker to create spots on the top of the shaft for drilling.
