Windmill with solar led lights that swivel in each blade.
This should be fairly easy to print. Designed so no supports are needed. Printed on anet a8 220mm bed but should fit 200mm bed if you rotate the part at a 45 degree angle.
: added high res filet edges blade (blade filet 45.stl) either blade works fine but using a brim will help keep it stuck to the bed.
Parts to print:
5 - blades
5 - LED holder rings
1 - blade hub
1 - base
1 - tail fin
1- base to pole spacer rebar ( this fits over 1/2" rebar I use for a pole and
inside 20mm hole in bottom of base).
Note - A 3/4" or 19mm pole will fit with out spacer.
Parts to buy:
2 - 608 bearings (skate board bearings)
1 - 5/16 or 8mm bolt, 2-nuts, and 3-washers, 5" or 125mm length (for hub shaft)
1 - pole to mount on. 1/2" rebar I had laying around or 3/4", 19mm dowel or?
5 - LED stake lights (55 or 56 mm, or a little less then 2 1/4" diameter. height
27 or 28 mm, a little less the 1 1/8").
Heres an amazon link to LED light but I get mine at Family Dollar store for $1 each.
Phycodelic Funky Town PLA works fine but ABS or petg will last longer
*use brim on blade.stl if you have problems with end lifting off bed.
Clean up printed parts with sand paper or file.
Press one bearing in each side of blade hub ( might need to sand or file to fit bearings)
Fit blades in blade hub (file and sand to get a tight fit but be careful not to force or blade hub may split apart).
Fit Led holder ring into blade (insert one side of ring into hole in blade then squeeze ring into oval shape to fit other side of ring in hole in the blade.
Push LED light into LED holder ring solar panel side first so light hangs down and solar panel faces upward. might have to clean up lip on LED ring so it snaps over edge of light to hold light securely.
Attach blade hub to base with bolt, put washer between blade hub and base, then washer and nut on after inserting in base. Use a second nut to secure first nut so it wont loosen up.
Attach tail fin. Just push into 10mm hole
Mount on a pole and adjust blade angle. 15 degrees is optimal but will spin way fast, might try 30 or more to slow it down. You can super glue the blades in place but I havent yet.
