About this 3D model
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
