wanhao duplicator i3 40mm pla cooler

here is a great 40mm alternitive to the stock cooler.
i printed it in pla and tested this on some long builds (12 hours+) and no melting . worked great..

i also added a lowered one . its 0.50mm lower to realy get it as close to the plate as posible without running into things on the plate.
(printing this one now and will report back how it does.
