Did you 3D print this model?

3D model description

This is a Grid for led strips with 60 leds/meter. It can be built in a 18x6 or 27x6 configuration. Of course one could build it as 36x6 or even bigger but that's soon getting out of reach for most Arduinos.

Supplied sketches/instructions are for Arduino Pro Mini/Nano, DS3231 RTC modules and WS2812B LEDs.

Instructions and printing tips (video) can be found here.

Features:
- 12/24h format selectable
- Different color palettes/modes
- LDR support (automatic brightness reduction, sample code for gl5516 included in sketch v4)
- Settings stored to eeprom (once set using the buttons)

Sketches:
Basics_v1
This one shows the basics of how to use the grid. It's a regular "horizontal zig zag" starting with data in at the bottom left corner (x/y 0,0).

Sketch_v4
The clock sketch as it can be seen in the pictures. Sketch_v4 supports 18x6 and 27x6 grids. Adjust RESX/RESY inside the INO sketch accordingly.

Sketch_v4 is based on the Retro 7 Segment Clock, further informations can be found there.

Usage instructions:
Button A
short press: Select brightness level
long press (3 sec): Switch color mode (gradient / solid)

Button B
short press: Select color palette
long press (3 sec): Switch 12h / 24h mode
Press Button A and Button B at the same time to enter setup mode. There you can use Button A to change values (hours/minutes) and Button B to proceed to the next (hours first, minutes, done).

If setup is run in 12h mode a dot in the upper left corner will indicate AM, lower left corner will indicate PM.

3D printing settings

Walls are multiples of 0.6mm. So I recommend printing using a extrusion width/wall width of 0.6mm/1.2mm. Link to a video showing this in Cura can be found in the instructions.
