Leapfrog 3mm fan spacer 40x40

This is the fan spacer from zabana's Creatr energy chain but this one is 3mm high. Reason is that my fans have connectors behind them to make a "quick release" of the printhead possible without unscrewing the 8 fan-bolts first.
Now there's just enough room for the connectors and they still help to getting the fans more quiet.
