max7219 스크롤바(with esp32-c3)

This is a scrolling guide bar using the MAX7219 LED and ESP32-C3 module. It can also be used for various other purposes depending on the user

The method for connecting the module and LED is explained in detail in the link below

I am providing the case model. Although there are many case prints for the MAX7219, I created my own because I couldn't find any designs that stood out

Using the ESP32-C3 model allows connection without tucking the charging cable inside, unlike other products

The front part uses PETG Translucent to enhance clarity. Print 3 layers (6mm) with a transparent filament

You can change the filament for the rest. However, PETG must be used for adhesion

Alternatively, you can print 3 layers of white PLA and change the color with the remaining PLA. This method

has a slight disadvantage in transparency

This is a video of the production process

By bending the pins for the connection between the MAX7219 LED and the chip, some unnecessary steps can be avoided

Detatch the Type-C port part from the print and secure the C3 with a hot glue gun. It is designed to produce a clean print

The LED bar is designed with an angle for good visibility
