Materials:

Assembly:

Base:

• Place the M3 inserts for mounting the sides

• Place the M2.5 inserts for mounting the RPI and the LED mount

• Mount LED strip to LED mount
• Use 2x 2.5mm screws to mount LEDs
• Use 3x 2.5mm screws to mount RPI
• Connect LEDs

• Mount sides using 8x 3mm screws (The logo side includes the difuser and difuser shield)
• Optional the support material in the base can be removed to route the cables
• Add the rubber pads

Roll:

• Use the M4 screws to mount the lock to the roll (Optional a ball bearing can be used) When using a ball bearing the roll may unwind itself. If this happens you can tighten the M4 screw or remove the ball bearing.

Cooling:

Tested with the Raspberry PI 3 B+ without problems. But the board gets pretty hot with the upside mounting position and no airflow. For the model RPi 4 forced cooling probably will be necessary.

OctoPrint plugin:

Use the excellent  “WS281x LED Status” plugin to control the led strip.

Tested with the SK6812W leds. Reduce the brightness to reduce power and extend lifetime LEDs
