2 by 4 Lego Brick

This is a regular lego 2 by 4 brick. The pictures that are messy just haven't been cleaned up yet. They are tricky to print if you want it to be clean and depending on which way you print it (upside down or right-side up) different parts will turn out cleaner or messier. It depends on your preference and doesn't matter too much.

I used a Makerbot 3-D printer for this print. My splicing software is Makerbot Studio. I recommend printing it in PLA at 190 Celsius-210 Celsius. Layer height is .1mm for fine details or .2mm if you need speed. Infill is 20% at lowest recommended (you can probably go lower as there isn't much to infill. You could also do it at 100% infill for a sturdy piece). Supports for the piece are a must. If you have a heated bed, I recommend you use it anyway to make sure you get good adhesion.
