<strong>Step 24:</strong> When a .stl file is loaded in PrusaSlicer, the software doesn't always get the orientation of the object correct (as in the first screenshot below). You may need to rotate your egg in order to put it in the correct orientation for 3D printing. You can use either the Rotate function or the Place on face function; both are located in the left-hand toolbar. Rotate the egg to ensure that the bottom of the egg is on the build plate.

<strong>Step 25:</strong> Configuring your print settings for a 3D print is often a mix of objective and subjective decisions. Using the "right" print settings can make a big difference in the final quality of your part. Certain print settings may make the part fail entirely. The print settings used in this tutorial work for the 3D printed egg shaker, but they may or may not fall into the category of "general best practices for 3D printing." Disclaimers aside... In the right column, use the three drop-down menus to select: 0.15mm QUALITY and Prusa PLA. Select the correct printer (MK4 or MK4S) based on which printers are available. In the Supports drop-down menu, select Support on build plate only and allow PrusaSlicer to enable the Detect bridging perimeters feature. Set the Infill to 15% and check the Brim box.

<strong>Step 26:</strong> Now go back to the Plater. Click the icon with a brush, this is the paint on supports option. You can then click Automatic Painting, however if there is a certain way/place you want your supports you can manually paint it on.

<strong>Step 27:</strong> In the left column, choose your print settings, typically best to choose from 0.15mm STRUCTURAL or 0.15mm SPEED, filament, typically PLA, printer, check availability and choose between mk4 or mk4s, and supports, depending on part choose everywhere or from build plate only.

<strong>Step 28:</strong> For this part, we need the print to pause about half way through so we can fill it with beads. Drag down the slicer on the right to the point in which you want the print to pause, then right click the orange plus icon and click add pause, you can them name the command.

<strong>Step 31:</strong> If everything looks good, click Export G-code in the bottom right corner and save the G-code on an SD card. You are now ready to take the SD card to one of the Prusa 3D printers and begin your print (make sure the MK3/MK3S on the printer matches what you selected in PrusaSlicer). Log your print and use the dry erase markers to record your contact info and print duration. Clean the build plate with a few drops of alcohol before you start your print.

<strong>Step 32:</strong> It's a good idea to monitor the print's first layer closely. Ensure the first layer is adhering well to the build plate. The transition between the first and second layer occasionally requires attention as well. The print fan often turns on after the first layer is completed. If the fan speed of the print fan is too high, the nozzle/hotend will not be able to maintain the correct temperature for extruding. If the nozzle temperature stays more than 10 degrees below its set value for too long, a thermal runaway error will occur and the part will fail. The fan speed can be adjusted using the Tune menu on the printer as the print is going.

<strong>Step 33:</strong> When the print pauses, add in your material of choice, I uses craft beads. You are welcome to experiment with different shaker materials for various sounds and loudness. The internal volume of the egg is approximately 71ml, so 15ml of shaker material is a good place to start since it fills about 21% of the internal space. Ensure that the height of the shaker material inside the egg will not interfere with the movement of the nozzle/hotend. Resume the print and check on it periodically as it finishes.

<strong>Step 34:</strong> Once the print finishes, remove the entire build plate from the printer (it is magnetically held in place). Gently flex the build plate in various directions to loosen the print. Use your hands to pull the print and support structure off. Only use the scraper as a last resort for removing the print. Scrapers damage the build plate and shorten their lifespan. Reset the space for the next person who will use the printer after you.

<strong>Step 35:</strong> Remove all of the support structures from the egg and recycle them or throw them away. Use some sandpaper, hand files, and/or the [[Belt/Disc Sander]] to smooth out the places where the supports made contact with the egg.
