NFC door lock system case

i faced a problem forgetting to lock the storehouse door

that's why i decided to make this project

materials needed are: 

1 Arduino uno

2 sg90 servo motor

 3 RC522 NFC module

4 jumper wires

5 TFT screen module

6 M3 insert nuts 8 pcs

7 M3 screw 8pcs

8 LED lights 2pcs (1 green 1 red)

i will publish a YouTube video soon as possible so you can get the Arduino programing code and wiring diagram and watch the procedures step by step 

i have added the circles on the edges to benefit the bed adhesion otherwise it'll snap off the heating bed

i will add a gecode file if you want to print it directly with my settings
