Maker Select Plus / Wanhao Duplicator Plus Hotend Fan Bolt Spacers

The screws that attach the fan to my hotend in my Maker Select Plus / Wanhao Duplicator Plus bent. Those screws are apparently M3 x 37MM. I couldn't find those anywhere, so I purchased very common M3 x 40MM bolts, and designed this spacer to make it fit correctly. It goes in between the bolt and the fan.
