Useless Box

thingiverse

This useless machine is inspiration from https://www.thingiverse.com/thing:1258082 I wanted to learn to CAD mechanical parts that fit together, with some microcontroller involved. I redid almost all the parts from previous build but tweaked them to suit my needs. it turned out great. I also used snug fit hex m3 nuts and bolts. The original build used a spring. I used two small m3 screws for the hatch, and a rubber band to tension the hatch. Here is the video of it in operation: https://youtu.be/0K4xUlRV9QA You can leave a comment, or email me at a.nadeem89@gmail.com if you need help in building this. I used an Arduino MINI, A servo Motor 9g, a SPDT switch. The SPDT comm pin is connect to GND. The other end is connected to Arduino Minis GPIO 4. The servo is connected to GPIO 9 of Arduino.
