Thx for this great design, my daughter absolutely loves it.

I've put at 120mm computer fan in front of it, so the amount of bubbles is massive.
That, however makes another issue, the basin gets under the level where bubbles can be produced too fast.

In which program is it easiest to raise the walls on the basin?

i used rhino 3d to make the basin about twice as deep. then i realized that making it deeper then the blades will not get any solution when the level gets to low. so there is no way to solve that problem.

Thank you anyway for trying. I guess I'll have to design some sort of auto-refill, so it always stays at the same level. I'm thinking about something like the self-watering-pot system..

hi. im glad you like it. i used spaceclaim to make this but lost all my files when my hard drive crashed. so now i would have to remake this. i would try zbrush or blender to raise the basin walls. meshmixer would work too.

Printed at .2 with supports on both the bucket and blades.

The Cura supports weren't the best to pull off the blades and it took some light sanding of the fan hole but it's now loose enough to actually be pushed by the wind.

It could have been my settings, but the edges of the blades were a little thin and jagged. I ended up using a knife to straighten out.

I would suggest thicker walls when you print and maybe higher than 20% infill.

excellent! can you post a pic?

Which one works better? The original or this one?

I also scale it 6 time's bigger, but it is still to small.
Are the dimension's made in inch or mm?

the box is 23 mm wide which is about 1 inch wide. so if you scaled it up 6 x then it should be about 6 in wide.
and it wouldnt matter what i measured it in. u just need to scale it to whatever size you want. 6x 12x 24, whatever it takes. you should get a visual on the screen of the 3d printer software you are using. and you can see it as it is being scaled up...
but i made the size approx 162mm which is a lil over 6 inches. and i uploaded the files with the new dimensions..

Please excuse the superstupid question, but how do you print the fan blade ?

I've tried blade side down and blade side up with support and have yet to get a useable print.

did you try it with raft and supports? i included pics from simplify3d that show it in the process of being built.

Awesome! Happy to see that the parts are the right size now. Version 4.0 had incorrect sizes.

thx for that input. i checked v4 and it seems same size to me. what do you mean exactly?.

When I load it, the tray is ~20mm wide at it's widest point.
I suspect some metric / imperial conversion issue - I scaled it to be 2.54 times larger and it seems like a more reasonable size.

oh ya ok... i didnt make it to any specific size so you will have to size it to whatever you want. its always best to size things to your needs and wants.

What size have you printed it at? I tried 2.5 times but it's still too small.. Currently waiting on a 5x print.
Also the height of the arm holding the spinner up seems just a fraction too short - the blades on mine seem to hit the bottom (or it could be my printer is a bit out of whack..)

thx for your comment! you are right my friend! the blades do indeed touch the bottom. i dont know how i could have missed that! I i have corrected the problems with the base now! but i still havent sized it to any one size since not all 3d printers are the same. you will have to size it yourself. the box width is 23 mm. and the blades are 14.2mm in diameter.
thx again.
