Spins on 2 different shafts and has a working dual planetary gearbox!!

Measures about 8.5 in (22cm) long.

About:
This is a simplified TurboProp engine based off of the Pratt and Whitney Pt6 engine. It feature dual planetary gears to reduce rpm to the propeller. It has the compressor stages, stator vanes, combustions stage, turbine stages, as well as two seperate shafts to transmit the power.

Materials needed :
- It requires 2 of the N20 reduction gear motors, the makers electronics bundle, and 2mm*8mm self tapping screws. These can be found in the links below for the more exact specifications.

- Allen key for the 2mm screws, should have came with the printer.
- No need for superglue, but can be used if desired
- Tweezers or similar can be helpful for support removal

Supports:
I used these settings for this model.

On the main shell (front and back) as well as the combustion , the embedded rings where the stator vanes and planetary gears sit have overhangs on them, when it prints, it leaves a couple lines of slack since there is not support, I have accounted for this and they can just be ripped or cut off. The peices will fit perfectly fine without support there. Picture below of where I am mentioning. (blue are the overhanges)

Assembly instructions:
Caution: Would NOT recommend any kind of conductive filament, it may short the circut.

The PDF below has instructions.

Excellent model. Printed the different sections in different colors. Only issue I am running into is pretty tight tolerances with the motors installed. I am getting occasional seizing while they run and sometimes they will strip the driving gear's mounting hole to the point I have to print another one. Any ideas?

The designer has replied

@AutoDesigns

Which section is seizing? Both sections should spin easily without the motors in. From what I can tell from the picture it looks the the combustion peice is not fully into place.If this is pushed out both sections may not spin. In the picture, above the blue line I drew, that extrusion may have hanging bits of filament, that would cause it not to slide in completely. if you use an xacto you can trim it and it should slide into the groove and fix the problem. Let me know if this works!

@AutoDesigns

This is how it should look when seated

Nothing on that part, it appears to be right where the driving gear connects. I will try a few things and report back,

Hi. I have got some troubles with wires. All is assembled regarding the pdf installation guide but nothing happens. Only the light on the board works. Any ideas to help me please?

The designer has replied

@AutoDesigns

It looks like you have it plugged in correctly. Double check to make sure everything is completely pressed in. Check if the motors spin while not mounted, if they spin check if your two sections spin semi-freely when the motors are not in place.

@user_1213132937

I have the same problem and have done all of the checks and still only the light on the board.

No matter how many times I wash my plate and print it, this part always fails on the first layer. Do you have any suggestions as to how I can fix this? Printing on the a1 mini. A flipped version of this same part printed fine though.

The designer has replied

@AutoDesigns

If you washed with soap and water, another option could be rubbing alcohol. Slow down the speeds to maybe 30-40mm/s on the first layer . Let me know if this works.

Might be that my filaments are wet. Will post the results!

I only printed and assembled the model, so without a motor. Putting it together was very tight and the outer shell is slightly torn, but I am very satisfied with the result

same here, looks great as a static piece but the pieces don't spin very well, it's really tight. Surprised to see there aren't many people talking about that here

With some minor troubleshooting, I was able to print this successfully. An amazing model, indeed! The instructions are great and in-depth. Overall, highly recommend.

very small model, printed in 0.12 for a flawless finish, I just didn't include the electric motor and control parts

ended up with 2, one that motor works, and one doesn’t since tolerances are SUPER tight and had to do trial and error to get motor one to work but was successful in the end!!!
