Can you please do an impeller with a 3.17mm drive hole so it will fit a brushless R/C motor? or release an editable file so i can do it myself (tinkercad wont import files over 25mb)

Could you please record video ?

What would you be looking for in a video. Like the printing it self or the assembly?

video of the working turbine, flow rate, noise, etc.

Sure, I will upload it when I have some free time this week. Also keep in mind the noise will be affected by things like your motor, the speed, how tightly your motor is attached to the turbine, ect.

what type of motor is this for?

Hi, not sure what you mean in what type, but here I will tell you what I used and know. I personally used one that I salvaged from an broken portable vacumm(12v 3mm shaft). The hole on the impeller is of 5mm, but because of the bearing I added on top, you may take any motor and use some tape so it fits tight on the impeller, but I recomend greatly that the motor has screw holes on it so you can attach it easily on the holder. If you want a 5mm motor, I know that the Graupner Jumbo 750 has a 5mm shaft and works with the design. I would recomend you to find a motor in your house which has a good size(The one Im using is 36mm wide), salvage one from some old vacumm or just buy a cheap one from ebay. If you have another question please ask.

Sounds good, thanks
