Electric Drawer

This is a mini project of an electric drawer. Design and build/ made by MT.
Parts are designed by Solidworks
and coding by Arduino.

This mini-project was inspired by my friend's DIY secret drawer.
His drawer has a physical internal locking mechanism, which cannot be opened easily.
Then, I come up with an idea, make a secret electric drawer, which will automatically open the drawer only by pushing the hidden button. Thus, by the characteristics of the stepper motor, it can "lock" the drawer.

At first, I was thinking of worm gear set up. Yet, by considering the opening speed and the chance of being user-friendly ( still can open without power). I switch the design to a rack and pinion mechanism.
the rack and pinion was drawn/ designed to fit in the 3d printed stepper motor universal connector.

#After the printing parts, coding, and installation.
There is a few problem:
The grip of the gear can be improved.
Noise of stepper motor
Precision (Thinking of installing some e
