DIN Rail Mount for Gledopto ESP32 WLED Controller (GL-C-017WL-D) - Snap-Fit, No Screws

## DIN Rail Mount for Gledopto ESP32 WLED Digital LED Controller

A compact, screwless holder to mount the Gledopto GL-C-017WL-D (ESP32 WLED Digital LED Controller, 4 outputs) directly on a TS35 DIN rail in your distribution box or control cabinet.

### Features

- Snap-fit frame: the controller clicks in from the front, no screws needed

- DIN rail clip with spring latch: hook it onto the rail and press it down; to remove, pull the release tab with a flat screwdriver, just like a circuit breaker

- Everything stays accessible: buttons (Function/Reset, Restart), indicator LED and all terminals remain free

- Compact: 49.6 mm wide, which is less than 3 modules (TE/DIN units) when mounted crosswise

- Material-saving: large cut-outs in the base, about 20 cm³ when printed solid

- Prints without supports, back side down on the bed

- Fully parametric OpenSCAD source included: adjust tolerances, rail type, orientation and more in the Customizer

### Controller dimensions used

- Body: 94.6 × 45 × 17.5 mm

- Including mounting tabs: 108 mm

The end stops sit behind the controller's mounting tabs, so the controller cannot slide lengthwise.

### Files

- wled_din_quer.stl: controller crosswise to the rail (recommended). Cables go up and down into the wiring ducts.

- wled_din_laengs.stl: controller parallel to the rail. Cables exit left and right.

- wled_din_halter.scad: parametric source

### Rail compatibility

Designed for TS35 × 15 mm rails (1.5 mm flange). For TS35 × 7.5 mm rails, set rail_t = 1.0 in the SCAD file and re-export.

### Useful parameters

| Parameter | Default | Purpose |

|---|---|---|

| ausrichtung | "quer" | "quer" = crosswise, "laengs" = parallel to the rail |

| clr | 0.3 mm | side clearance; adjust if the fit is too tight or too loose |

| rail_t | 1.5 mm | DIN rail flange thickness |

| stop_h | 6 mm | height of the end stops for the mounting tabs |

| fenster | true | material-saving cut-outs in the base |

### Mounting

1. Snap the controller into the holder: press it straight down until all four hooks click over the edge.

2. Hook the top edge of the holder (OUTPUT side) onto the DIN rail.

3. Press the bottom down until the spring latch snaps in.

4. To remove: insert a flat screwdriver into the slot of the release tab at the bottom and pull down.

### Notes

- Use PETG or ASA. PLA is not recommended inside a distribution box because of heat and creep. I printed with PLA for testing, it depends on your environment. 

- Mount it only in areas where low-voltage DC devices are allowed, and follow your local electrical regulations.
