Hello, I have constructed here a holder for an Arduino Nano.
This is for the LED strip in the profile guide of the Ender 2 PRO.

The following parts are needed:

1x lower bracket for Arduino (see STL file).
1x upper bracket (see STL file)

2x ISO 4762 M3x16 screw
4x ISO 4032 M2 nut
4x ISO 4762 M2x6 screw
(depending on the PIN length of the Arduino a longer screw may be needed)

1x 5V LED strip
1x Arduino Nano
3x 10cm (5V suitable) cable

The whole thing is powered by the 5V connector of the Arduino Nano.
The LED strip is connected to the 5V connector of the Arduino.

An instruction and four color profiles are included in the download.
For color adjustment you need the "Ardino" software.

If you have any questions, please write me via the "Massage" function at Cults.

Information without guarantee.
I assume no liability for damages.
