3D Printed Motor Runs on Almost Nothing!

whoever uploaded the STL files didn't check them for scale. Quite an ugly disappointment, with a cavalier attitude throwing idiosyncrasy into the wind, without any care.

I give this design a big fat failure for a grade, from me.


What is the diamter of each coil? And how many time I need to turn the copper around it?

Thanks for your hard work Lasersaber. You always create cool projects and I have a blast replicating. I was able to print this with help from another person who made a couple small corrections in the STL files so they would slice properly to generate good Gcode. Thank you so much!

Just printed all the parts need a source for the sapphire vee bearing cups

How about version 3???

Hey I wondering if i could buy one from you

Great little motor. works just as you said. Love it, but was wondering if you are ever going to release version 3. been waiting for that one to try.

How much time is 'unbelievably long time' ?

I could tell you, but you wouldn't believe it.

what size should all the parts be the? scaling is rather strange every part is a different scale and defiantly would not work.

Ok, I got it done, as you can see in the photo.
Shouldn't it run when hooked up to a battery?
It is a motor?
Anyway I can't get it to start and run?
any help?

Thanks Ron.

Hi Lasersaber,
This project is fascinating. I want to make one. How much magnet wire should I get for the bobbins?
Do you cut the needle or you use it whole?
Thanks for a great porject

I want to make one of these motors so I started ordering parts.
But how much magnet wire do you need.
Is one 6125ft spool enough for a motor or do you nee more?
Let me know.

Please check the STL files.
Base, rotor and pin have to be scaled x24.5 in order to fit.
Also the bobbin bottom part has a diameter of about 15.25mm which is too big to fit this motor.
I turned them down a bit in a lathe to fit the outher circle of the rotor. Scaling inch <-> mm doesn't help with that issue.

Anyway - nice project!

I downloaded the files but when i place them into ReplicatorG and also Repeater-Host, the objects are extremely small.
If I scale them by 10 the object appears to be about 1.X inches.
The Rotor and BaseV2 are the two files I have tried.
Am I having a senior moment?

I noticed this same problem when loading the objects into MatterControl. I was able to correct it by setting the scale ratio to "inch to mm (25.4)". I hope that helps.


Hello sir.
I am extremely interested in your device and would like to purchase a finished version2;
i would like to use it in my project. Is there a way I can possibly PM you.
I also had some ideas I wanted to run across with you for your design.
