Hi! I am am a big fan of LEGO and I have come here today to ask for a new plugin/external program/script that is compatable with Blender that will take any 3D model and,following the LEGO physics (as in, all studs go up and stick on top of each other), convert it to LEGO bricks. The remesh modifier works for Minecraft style, but if only we could get a LEGO style. I have modeled a 1x1 LEGO Brick (link below) for you to use. Here is an example of LEGO’s official Brick Builder Software, and it’s awesome. 
This would help out the LEGO 3D community a lot! 
1x1 LEGO Brick (comes with a low-poly one, a normal one, and a beveled one):
1x1 LEGO Brick.blend (513 KB)
Thanks in advance!
