2Blade Windmill. Mandala-Effect. 2-part wheels, new spinner, new body

I redesigned and draw this Modell totally new in fusion360. The idea though is from

The wheels are now in two parts, so they can be printed on an mk4 size printer They snap together at the base and the 2 outer parts. A few drops of CA are needed

The pockets for the bearings are integrated for a proper seat. No rim or similar is needed- At least with PLA with smooth pei sheet and satin coated sheet.

The spinner now ads a nice illusion with the spiral. I painted it with a white acrylic pen. The fake screws are painted with a chrome-pen. Only 2 real 3mm screws are needed.

The body is designed for an easier print. Most important is the possibility, to place some weight in the tail. 

If properly balanced, it doesn't matter if it's mounted absolutely perpendicular .

(notice: My prototype had 2 fins. but one is absolute sufficient)

Most important is to have the 2 bearings for the wheels moving as easy as possible so the slightest breeze will turn them.

There is an additional joiner if one has to connect two 8mm threaded rods, like I had to :)

aditional hardware:

 1m threaded rod

 3mm screws for the spinner, 

 8mm screw, min. 60 mm long

2x 8mm nuts , for the base.

4x ball bearings. 608   8x22x7 mm. I used ones without seals, because they move a lot easier.

the wheels printed in pla. Rest in prusa Petg.

The long part of the 8mm rod is used for the “stand”. Cut off a 100mm  part for the upper part to mount with the 2 bearings, 2 nuts and the spacer. (see pictures)

The fin and base have to be glued (CA or similar). I joined the tail and the front part only with black tape, so it can be taken apart.

after adding sufficient weight in the back, make shure, that the weight (i used small lead balls)  does not move around. (I stuffed some  soft packing material in there.) In addition there is the cap to close the hole.

have fun.
