Replicator PLA cooling fan mount based on jer's design but redone using lofts in sketchup to smoothe the lines and made it unmountable. I need a better fan than I have to test it out. also included a 60mm to 40mm fan adaptor to fit a bigger fan. Finally got a design that will allow mounting a 60mm fan and not catch on any bodywork.Printed fine with no raft and no support. I used support for the 60-40 adaptor but it printed so little I might have got away without.
