Windmill - 8 Blades

thingiverse

Very nice 8-blade hub design by Michaelmi782. Remixed hub features low-friction races, 3mm long at each end. I used a #42 drill bit on the center hole. Base Mount: Clean center hole with #35 bit for wire or other suitable material. I dropped a small piece of metal (finish nail head) into the bottom of the center hole for reduced friction. I used a bead between the mount_pipeV3 and the printed frame. Several tail sections are provided, however any object 2.5mm thick may be used. Wire: Wire clothes hanger (2.4mm) or a piece of 3/32 brass welding rod (2.5mm), 110mm long will work just fine. Frame: I used PLA at 220 degrees. First 30 minutes at 100% speed, balance of time printed at 72%. Faster speed makes the stem hole smaller where slower speed will make it larger when printing one frame. Allow stem to cool completely before working it. Your results may vary. Clean wire holes with a #42 index bit and press 110mm long wire rods into position. Holes in the tail section are for pinning the tail section with 1.75 mm filament. Clean with index drill bit #49, v-notch is center line. There are many variables, so you will need to work with the components. I use a drill press for accurate holes. Fit up necessary. Lubricant and balancing of components will make it move smoothly. Placing the blades smooth side to the wind will be more efficient. Stock blades are available at http://www.thingiverse.com/thing:950635.
