Update: Added Motor_Plate_12-19-13.stp, Motor_Plate_12-19-13.igs, Turbine_12-19-13.stp and Turbine_12-19-13.igs. I've had requests to add solid files for the motor mounting plate so people could modify it to fit their specific motor.

This turbine blower assembly was inspired by http://www.thingiverse.com/thing:39755.

I had some problems finding the right motor/gear combination so I modified the turbine so that it could fit a common 9-18V electric motor. I believe I used a Radio Shack# 273-256

The upper housing has added support in the output tube that can easily be cut out.

3/24/14 - Added solid models! Enjoy!

The hardware required is:

7 M3-.5X10mm Socket cap screws.
7 M3-.5 Nylon Lock Nuts
14 M3 Flat Washers

and 2 screws for the motor. I don't know the exact size. I couldn't find them at the Home Depot. I robbed them from a junk laptop I had in my basement. (Possibly M2 or M2.5?)

I'm going to build a miniature vacuum cleaner. Would you imagine this would provide a good amount of suction into the turbine, given a 18,000 RPM 12V DC motor?

What kind of vacuum are you trying to achieve? I don't have my turbine to test anymore unfortunately. My first thought is that 18K RPM may be a little weak. You might be able to find a faster motor from an RC hobby shop. Using brushless motors would be crazy fast, but a lot more expensive. Check out some of the makes. There are a lot of different motors being used.

The impeller looks fantastic! I can't figure out the casing, though. I've seen a bunch like it tonight...and it just strikes me as wrong. There is supposed to be a tight-clearance section between the intake and exhaust. But there seems to just be a large open chamber. Maybe there's something I'm not understanding, but it appears that the efficiency could go WAY up with s proper shroud. Do you know what this design is based on?

This design is just a simple centrifugal blower. I designed it to look like an automotive turbo charger, in 1 evening, just for fun.

It works surprisingly well, but there's always room for improvement.

Luckily It's open source! I included editable files - I can't wait to see your remixed design. hint hint

Will the turbo make boost at all? crank it up to like 20,000 rpms?

The Roomba 980 now has one of these. Very excellent design.

Hi great work! can you upload STP file Step file if you got any. thanks

Hey there what is the actual size of the turbine and all the parts i think mine is too big

The turbine should have a 66mm diameter. What is yours?

mraza123 - in reply to johnnyrobot

65mm in diameter thanks anyways.Im wonder why is the base moter mount is very huge here a pic
Sorry for the bad Quality

I would recommend using a different slicer. I used slic3r at first. Then I moved to Cura. After Cura, I went with Simplify 3D

so anyone having trouble printing the turbine. My machine jumps or stops around a lot in the fins when filling in and it makes it really rouph looking. I'm using slicer3r so any suggestions?

I would recommend using a different slicer. I used slic3r at first. Then I upgraded to Cura. After Cura, I purchased Simplify 3D. I've been pretty happy with S3D


I can't figure out how to rotate my design in Alibre Design. Have you tried Cura yet? I moved from Slicer to Cura because I was able to rotate stl files.

I'll see what I can do.

Can you upload an stl file of the upper housing so that it lays flat? I can not figure out how to rotate it in slicer.

No whistle sound. It's just a blower.

okay tnx just what i need :)

heey dose it make that whistle sound ??
