Advice for new designers:
- Octagonal holes are quick to model and print accurately in a vertical orientation
- Pins, axles, or anything long and thin will be stronger if you shave off one side and print it flat on the build plate
- The Fusion360 pattern tool in sketch mode is slow and sorta broken, you should pattern features or bodies instead
- Thin (1-3mm) walls are usually fine

Advice for new printers:
- Pick up your build plate by the edges, keep your oily human fingers away from the center
- Wash your build plate with dish soap and rinse
