Project is based on Reprap Forum thread, where i found inspiration and connection diagram to make my own screen.

I found necessary components that does not require soldering and made ergonomic housing for easy control of 3d printer.

• OLED 0.96" i2c screen
• Encoder module
• SD Card reader module (SPI)
• M3x12 6pcs
• M2x20 4pcs
• M2x12 4pcs
• M2.5x8 2pcs
• M3x16 2pcs
• OD 10mm cable chain (optional)

Printed parts (any material of choice, PETG recommended):

Overall mount directions:

Base attaches all 3 modules, so assemble them at first Lower cover and internal link needs to go second Upper cover and cable clamp third At last knob is to be press fitted onto encoder shaft

Preferable Marlin 2.0.9.1 (tested and working). Newest Marlin version might require changes.

In file Configuration.h you need to specify:

#define U8GLIB_SSD1306
// DIY TinyOLED https://reprap.org/forum/read.php?13,499572,page=1
#define TINYOLED

Changes in pins_RAMPS.h (changes also should include "cleanup" of unused code loops, for it otherwise might not work):

#if ENABLED(TINYOLED)
  #define BTN_EN1 33
  #define BTN_EN2 35
  #define BTN_ENC 31
  #define BEEPER_PIN -1
  #define LCD_SDSS 53
  #define SD_DETECT_PIN -1
  #define KILL_PIN -1
#endif

Lastly add lines in Conditionals_LCD.h:

   #elif ENABLED(TINYOLED)
     #define DOGLCD
     #define IS_RRD_SC
    //  #define IS_ULTIPANEL 1
     #define IS_U8GLIB_SSD1306

Firmware (Marlin 2.0.9.1) can be found in miniprusa MC3 project files.

Wiring is the same as with TinyOLED:

Want to contribute? Great!

To do:

• add internal cutout to upper cover for longer OLED pins
• make changes to base to ensure ease of printability (supportless if possible)
• ensure proper dimensional tolerances for M3 screws on the upper, lower covers
• additional instructions to implement on newer Marlin versions
