Anenometer

This is a start of a wind anemometer other parts soon to follow . it has golf ball dimples for drag reduction . To make it easier to print and slice ,2 stl files comprise one wind cup.. that was the only way i could prevent the file from slicing improperly for some reason unknown ? Im working on the hub and bearing so far i have just printed the cups. as i complete each part i will upload it so more parts should follow . .... Added a larger way to print the cups attached to the hub haven't tried printing it yet im going to try printing in carbon fibre nylon , on a larger 3 d printer . if you have a 6 inch printer you have to print separate cups.
