NASA Logo

I remixed this to be printed on a single extruder printer.The way I do it will only work on a printer with a BL-Touch type probe that will hit the direct center of the bed. Each color is a completely new print. DON'T LET THE BED COOL DOWN BETWEEN PRINTS or the tips of the red will start to curl up. Don't peel off the purge line either. Once the entire logo is printed in blue (one piece logo), send the next color as a new print and the probe will hit the blue and think that is the Z-zero of the bed and print the new print on top of the blue full logo. It just so happens that the probe will only hit the blue unless your build plate is a different size and Cura centers it different than on an Ender 3.I print this right side up versus the original being upside down.I tried doing all three colors, upside down, on one layer but it doesn't come out very well due to typical first layer type issues that would normally fix themselves in taller prints, but because this print is only two layers (if all colors are on the first two layers) then any slight defect doesn't get resolved and is visible on the final product. Things like one little white star might smear, etc.The way I use the attached STLs is to first print the full logo in blue only, this gives a good foundation for the red and white. The blue is the base. Then print the white on top, followed by the red. So the red and white are on top of the blue and the same height as each other for a total height of .08. Printing red on top first or white on top first both have their advantages and disadvantages. No matter what I've tried so far there is a "little" bit of the other color that gets dragged over the other colors. Trial and error. It still looks really good though.Blue will be .04 high, you could print it twice for .08 if you wanted a sturdier end product.Red and white will be .04 high on top of the blue; total height, .08I have an Ender 3 and the STLs need to be scaled to 90% to fit. There are four very tiny dots on each corner of the STLs so each one will center perfectly on the build plate using Cura's, right-click, "Center Selected" once scaled to 90%. They will also be perfectly aligned with each other. The corner dots on each STL define the dimension of the print, each STL has the dots in the exact same location. The dots don't print because they are so small, that was on purpose. Only scale the X & Y to 90%, leave the Z at 100%.I used Overture, Red, White, and BlueMake sure your bed is really level or you have a good bed level mesh.210 degrees hot end70 degrees build plate to help keep the tips of the red from curling up off the bedI've included the Fusion 360 file, STEP files, and STL files. Note that the separate bodies in the Fusion and STEP files don't have the little circles in each corner (so they won't center correctly in Cura) but the bodies in the Fusion component do. You should only really need the STL files, they are ready to go other than being scaled to your print bed size. I included design files for the remixers out there.
