This is the base of the cube. The sensor is placed in the small round hole, the LED strips stick to the inside of the posts and the cables are inserted through the middle part. A reflective film has been applied to this area, which helps to spread the light around. A diffuser (plexiglass) is slid into the furthest slot and a plywood wall, with or without directions, is placed in the nearest slot.
This is the bottom of the cube. This is where the PCB, battery holder and cables end up. A hole is provided for a USB cable as secondary power. These 2 prints are screwed together with an M3 screw or bolt.

The PCB consists of a pair of connectors for the ESP, LED strip, sensor and USB-C port. These are female headers, so they fit in perfectly. The connectors are internally connected on the PCB.
The circuit consists of 1 ESP, powered by a USB cable or a 5V battery pack connected in parallel on the j1 connector with a diode from battery pack to connector (4 rechargeable AA batteries). 3 female headers for the LED strips, 3 female headers for the sensor, 8 female headers for the USB-C port and a diode to stop current to the batteries.
Measurements: U LED-strips (off): 4,1V; U LED-strips (on): 3,1V
U Batteries (leds off): 4.9V; U Batteries (leds on): 4.3V
U Diode (leds off): 0.72V; U Diode (leds on): 0.86V
U Sensor (leds off): 2.98V; U Sensor (leds on): 2.55V
U ESP (leds off): 4.1V; U ESP (leds on): 3.45V

It measures 52.2 × 43.6 mm and has 2 copper layers, 1.6 mm thick.
10 parts, built around the ESP32-C3-DEVKITC-02. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the vives-project-xp/EOMarkers repository on GitHub, at the commit this page was made from: the board is PCB/PCB_ESP32-C3-DevKitC-02/PCB.kicad_pcb and its schematic PCB/PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask vives-project-xp before reusing the design.
