Brix

First of all - this is not a Lego and will not be from original model. 

This project is a alternative for Lego, for makers. Bricks fit very tight, You'll sometimes will need a flat head screwdriver to separate them. Thats why 4 holes on each part.

Project was made from scratch and was not based on Lego pattern. It looks simmilar but is different in many places. I saw it right before the end and was shocked, because it would have saved me lots of sample printing :P

Base project comes with bricks and plates only, with various sizes:

You can make anything with them :)

Bigger ones from top picture are scaled up ones, which is specified below.

Now onto print settings:

Top/Bottom layers - 2

Walls - 2

Infill - 2%

If You will rescale it, You should multiply those by scale factor - 300% is 3x the value

Model has a lot of parameters, which will help You make custom sizes. It even comes with “size” parameter which will scale the model (original is 10 as for 10mm per unit of others):

Every block comes with prebuilt brim, because holes on sides will make slicer create them inside holes. If You wanna delete it, You need to download f3d file and hide last extrusion:

I will make later parametric models of other pieces like slopes, semi circles etc, but this is base for everything. Feel free to make it Yourself :) F3d file has everything You need :)

I think I described everything. Have fun and Happy printing :)
