3. Do I have enough time to make this properly?

#### Get started!

1. Book a printer.
2. Export your design from Fusion 360 as a STL-file.
3. Open Prusa Slicer.

5. Upload the STL-files and place them reasonably.
6. Choose which surface to place on the bed.
7. Make sure every part lays flat on the bed.

8. Usually these settings are good for printing:
9. Does some parts need support?
   1. "Support on build plate only": support from bed.
   2. "For support enforces only": support from a part of the print.
   3. "Everywhere": a) + b)
10. Press the button "Slice now" and look at how it will be printed.
11. Export the print as a G-code with file name " firstname number"
