Why 3D Printed Motor Housing?
I was not very happy and was tired of using hacked motor and motor housing from toy car or toy R/C car, because each time I want to build a different design Lego Cars. Most of the time the new design Lego car that I plan to make was not able to use the previous hacked motor and motor housing.
Now that I created my own 3D printed motor housing. My motor housing for custom LEGO® car can be used over and over, and I do not have to buy toy R/C car to hack for motor housing from it and mod it to fit with my new design Lego car anymore.
This 3D motor housing was designed to have studs (4x6 studs) that compatibles with LEGO® modular system.
printed motor housing fits most of DC gear motors (130-Size), standard toy DC motors, with the approximate size of 15x20x25mm (height x width x length) with 2mm shaft diameter.Photo 1

The 3D printed motor housing used in this project was first created in 123D Beta 9, and then migrated to 123D Design, both have the similar functionalities. The 3D printed motor housing was first printed from The Free 3D Printing offer from instructables.com (now closed).Photo 4, 5, 6

Here are the steps I made to create 3D printable motor housing in 123D Design
Before I migrated from 123D Beta 9 to 123D Design I tried out the 123D Design app. by created 130-Size motor in the 123D Design first.Photo 8
Then I created 1x4 LEGO Brick.Photo 9
And then added Primitives, and used Combine tools to form the housing.Photo 10
And 3D Printing ready model.Photo 11
I hided the motor model and ready to send to fabricator.
