turning and beeping TF2 sentry gun

thingiverse

Here is a USB-powered sentry designed for a 28byj-stepper, a 30mm speaker, and electronics. The lid of the magazine can be removed to accommodate these components. To make it work, the stepper's screw hole tabs will need to be trimmed down to fit snugly. Many parts require sanding or adjustment in the slicer to ensure they fit properly. This is because the sentry was originally designed to be printed at a larger size. If you spot any critical issues, please don't hesitate to point them out.
