I printed ustkl's 1:1 lego figurine, but I ran into issues with some parts being too loose, the same issues other have had, based on the comments. I also was bummed that you could only print the whole guy, not individual parts. Finally, I thought it would have been nice to have the source file to play with..
So I fixed all of that. I made the neck standard lego size, the hips fit better in the body, but also a better fit for the legs, I made the shoulders hold better in the body (they take a bit of force to snap in, but they are now solid), and I also uploaded a head I designed that have a ridged neck hole that fits perfectly in standard legos. essentially, the only part I didn't touch was the torso.
ALSO, I split all the parts into separate STLs, and added the 123d file I used to play with. some of the body parts I was not able to convert back to solid shapes (hips, both arms), but at least they are separate from the rest of the stuff so you can play with them.
just for fun, try mine, and try this one; I don't know how his fits all together but it looks really good, so.. https://www.thingiverse.com/thing:1224589
If you like the remix, please LIKE IT. feel free to COMMENT or I MADE IT. all feedback is welcomed. please keep in mind I didn't make it, just fixed some stuff to the best of my abilities.
**edit: added the stand alone head.
