PicoStepSeq: MIDI Step Sequencer w/ Raspberry Pi Pico

PicoStepSeq is an 8-step MIDI sequencer using a Raspberry Pi Pico, an I2C SSD1306 OLED display, a rotary encoder, and 8 LED "Step Switches".
 

The enclosure design references the music gear of the late '80s.

Printing: 

• Top part:  In the slicer, flip it over, and print upside-down with supports. (use support enforcers to reduce print time). If you want two-color printing of the top bosses, put a layer change at layer 4 & 7.   
• Bottom part: just print
• OLED spacer: print with nubs up. It goes under the display to support it
• 0.2mm layer for all pieces is fine.

Parts needed ,in brief:

• Raspberry Pi Pico
• I2C SSD1306 0.96" OLED display (amazon affil)
• 8 “step switches with LED”
• 1 rotary encoder
