This is a Danger: Science in Progress sign.  It doesn't do anything, it's a decorative sign for your lab bench. Print it in glow in the dark filament for a faux radioactive glow.Filament colors (assuming .20 layer height):Layer 1-8 – 0-2mm – White/natural/glow-in-darkLayer 9-10 – 2.0 - 2.4mm – BlackLayer 11-12 – 2.4 - 2.8mm – RedSlicing the fileCura (as of v4.13.1):Load model, orient with back flat on the print surfaceOpen the Extensions menu, select Post Processing > Modify G-CodeClick Add a scriptSelect Filament ChangeEnter Layer 8 as the layerClick Add a script againSelect Filament Change againEnter layer 10 as the layerClick the Close buttonSlice the model and export the g-code fileGo back to Modify G-Code and delete the two filament changes since they persist across sessions in Cura, and you probably don't want that.Load the file in your printer and be prepared to swap filament when prompted by the printer or Octoprint.PrusaSlicer (as of v2.4.1):Load the model, orient with back flat on the print surfaceClick on the Slice now button in the lower right corner.Scroll the layer height slider to the right of the print preview down 4 layers (assuming .20 layer height).Click the little plus button on the height indicatorScroll up two layers (two from the top layer)Click the little plus button on the height indicator.You should have two colors on the the model and the height indication scroll bar.Click Slice nowClick Export G-codeLoad the file in your printer and be prepared to swap filament when prompted by the printer or Octoprint.Print SettingsPrinter: Ender 3 Pro w/ direct driveRafts: NoSupports: NoResolution: 0.15-0.2mmInfill: 15% or higherShells: 2+Notes:Printing with different colors will need manual filament swaps or a Prusa MMU2 or equivalent. For manual swaps your printer will need #define ADVANCED_PAUSE_FEATURE enabled in the configuration_adv.h file in the Marlin firmware to enable M600 commands. This is typically not enabled on the factory firmware from Creality. Prusa probably has it enabled.
