Automatic alarm clock turret
Description
3D MODEL DESCRIPTION Automatic alarm clock turret for those who are no longer helped by a regular alarm clock. If you don't turn it off in the allotted time, then it will douse you with cool water. The turret is built on NodeMCU, so it can be controlled via wifi from a phone or computer, right from the browser. The turret is equipped with an auto-guidance system based on a pyroelectric motion sensor. However, you can use a more advanced version of auto guidance: by camera, using OpenCV, if you have a raspberry pi available.

Support is required only in some problem areas for some fasteners or at the joints of parts. I recommend printing the parts as they're set in stl files. Nozzle - 0.4mm. Layer height - 0.2mm. Speed and Infill should be chosen as you see fit.
