I am constantly in search for a particular rare brick from the 1990's which is ridiculously expensive on BrickLink and also hard to get. So I am thinking about printing it on a 3D printer to be able to finish projects. I understand, a blasphemous behaviour. Please let me know where to get the needed 3D file.

    LEGO doesn't (3D) print their bricks, especially not in the 90ies where 3D-printing (almost) wasn't invented yet. So you're looking for a file some random person has made for his/her own use. I've never seen a repository of such files. – Henrik Feb 20 at 11:53
  • well, i thought there are 3D programms that one can use for designing models and there is a library for the bricks. i would like to extract the one brick as a file. btw, the brick is in use also today but not in the color that i am looking for – fabian Feb 20 at 12:05

    What part are you looking for? – chicks Feb 21 at 17:41
  • hi chicks, I am looking for "6192 - Brick, Modified 2 x 4 No Studs, Curved Top". It is a common piece but not in white. It was only used in 1995 in 3 sets. It would be great to have a STL so I can print it – fabian Feb 24 at 20:01

The canonical location for 3D models of LEGO bricks would be LDraw, with its huge catalogue of official parts.

Another resource specifically catered to the 3D printing community is PrintABrick. Their library is not as big as LDraw's, but they offer ready-to-print STL files.

    LDraw files are suitable for digital modeling, but not for 3D printing. – Alex Feb 20 at 13:55

    @Alex Good to know! What renders them unsuitable for 3D printing? – zovits Feb 20 at 14:21

    LDraw parts have just geometry. You still need to tweak dimensions, tolerances and directions after conversion. So they are not ready to be used directly for 3D printing. – Alex Feb 20 at 14:44

    I am not sure if I understand your answer Alex. My friend with the 3d printer says that he needs STL files. Would I be able to produce those with LDraw? – fabian Feb 20 at 18:05
