Introduction: 123D Design Lego Brick

Picture of 123D Design Lego Brick

In this instructable i will be showing you how to make a Lego brick i don't have a 3d printer so it hasn`t been tested but i am almost positive it will work. If you have a 3d printer please consider printing it for me i will leave the file below

Step 1:

Picture of

Dimensions of the main brick body Length: 31 mm Width: 15.5 mm Height: 9 mm.  Find primitives in the bar menu and select the cube enter in these dimensions 31, 15.5, 9.

Step 2: Placement of Studs

Picture of Placement of Studs

Firstly the studs have a radius of 2.5 mm and are 1.5 mm high. The studs are 1 mm from the sides, front, and back and 3 mm from each other. You may want to use a carpenters square to check that they are lined up perfect. 

Step 3: Bottom

Picture of Bottom

First you will need to hollow out the bottom go into modify then shell once in the modify menu. Now a mini bar should have popped up on the bottom of the screen in the box that says thickness inside type 1 then click on the bottom of the square now you should have a hollowed brick. Now grab the cylinder from primitives and set it with a radius of 3 and a height of 9 now place centered in the brick 3 mm from the inside on one end. Now shell it with a inside thickness of 0.5 place two more exactly the same 1 mm from each other shell them too. Now you are done your 123D design Lego brick now you can send it off for 3D printing unfortunately i don't have a 3D printer so could one of you please tell me how it works thanks.

I made it using Autodesk 123D. It was a great learning experience. Thank you. It's a little rough and out of alignment but I plan to place everything precisely on the next version.

Hi,
First, I want to thank you for the great effort for this instructable.
LEGO bricks have it owns standard dimension. So the bricks would fit together well. When we want to make our own 3D printed LEGO brick. We want to make sure that our 3D printed LEGO brick would fit well with the original LEGO bricks.
I made some mistake on my design, like the earlier version of the servo mount for LEGO (https://www.instructables.com/id/12-Thumbs-RC-LEGO-Dragster/#step1). And I wasted some money by ordered some 3D printed from the third party fabricator and it turned out that I could not used them with the LEGO bricks.

It seems to me that the dimensions of the brick is little off. My advice is to do some more research before settling with the dimensions.
Here are some links that I found useful,
http://www.robertcailliau.eu/Lego/Dimensions/zMeasurements-en.xhtml
http://en.wikipedia.org/wiki/File:Lego_dimensions.svg
or you could use the key word like, http://www.google.com/search?q=lego+brick+measurements&client=safari&rls=en&source=lnms&sa=X&ei=ZdsUUu3zKuHg2AWelYH4AQ&ved=0CAgQ_AUoAA&biw=1284&bih=705#fp=8fe0ec345e3f5309&q=lego+brick+measurements&rls=en&start=10
to find the dimensions of the LEGO brick.

Hope this comment is not discouraging you.
Sincerely,
sam
