🛠️ Installation Guide

Get seamless printing on any standard machine with these pre-tested STL files.

Overview

Keep the default orientation for a support-free print (only the display base and ESP8266 case will require supports), or use the 3MF file to easily customize your layout and filament colors. (STLs included for legacy slicers). The 3MF file is organized by print assembly order for simple guided installation.

Display Base

The ESP8266 case snaps into the display base, followed by the placement of the Display Back Tray. Once connected, the ESP8266 board can be placed into the case, and the LEDs can be soldered into place. Do not apply the LED lights to the display case until the Display Backdrop is installed. Just let them sit out and rest outside of the display base, along the edge.

ESP8266 D1 MINI & WS2812B LED Lights

This part can be done in several ways, and I highly recommend following the WLED wiring guide for reference on ESP8266 & ESP32 boards. For this demonstration, I simply connected the 3 wires from the WS2812B LED Strip directly to an ESP8266 D1 MINI board and flashed the board by connecting it to my laptop and following the easy 3-step instructions to install the WLED files to the board at https://install.wled.me/. Once flashed, the lights can be easily controlled with the official WLED app (available on Google Play and Apple Store). This clock can hold up to 20 5050SMD LED bulbs on the strip.

Display Backdrop

Install the clock assembly onto the display backdrop (if not using a clock, plug the hole with the second hand cap adaptor once the Display Overlay is installed). Slide the Display Backdrop into the Display Base until it fits snug with the open gap, pointing down over the ESP8266 case. Now the LED strip can be applied to the Display base inner trim, locking the backdrop into place. Tuck any loose wires under the backdrop around the ESP board.

Display Overlay & Top Trim

Place the Display Overlay over the backdrop and arrange it by spinning it until you are happy with the placement. The Display Top Trim can now be applied by snapping it into the Display base. If done correctly, the top trims diffuser should perfectly cover the LED strip and secure the backdrop in place.

Clock Hands & Center Cap

The clock hands are pretty straightforward. The hour hand (short one) goes in first, followed by the minute hand (longer one), and the second hand goes on last. I recommend popping the Clock Hand Center Cap onto the second hand before applying the second hand to the clock.

Display Stand

The logo is placed onto the Display Stand, which will need to have the logo plugs super-glued to it. I recommend snapping the plugs into the stand first and applying the glue to the plugs before placing the logo onto the stand. This will allow for easy removal later if you want to change the logo.

Top Trim Icons

Just like the logo on the display stand, we will need to glue the icon plugs onto the back of the Trim Icons. When printing these using an AMS system, these are designed to change colors by layer height, so pair the matching colors together and print them in batches. I have found this to be the most efficient way to print multi-color designs of this scale with as little waste as possible. These icons can be placed anywhere around the top trim as well as placed on hour/minute hands (I recommend one or the other, as using both starts to make the clock hands heavy, and it could affect the functionality of the clock.

Mount & Enjoy

Congratulations, you’ve managed to recreate an iconic HUD display from one of my favorite games. 3d printing and working with micro-controllers like these ESP boards are something I’ve been tinkering around with for over a decade. It brings me true joy to not only combine all of my hobbies into one tacky project, but to be able to design it in a way that others can create as well. If you’ve completed this build and want someone to share it with, I’d love for you to consider posting it on the download page you found it on, as well as tagging us on social media if you decided to share it there… I can’t wait to see it!

Getting Connected…

Controlling your clock’s neon glow from your phone is simple. WLED runs on its own local hotspot out of the box so that you can link it to your home Wi-Fi in minutes:

1. Download the App: Search for WLED or WLED Native on the Apple App Store or Google Play Store and install it on your smartphone.

2. Connect to the Clock: Plug your clock into a power source. Open your phone’s Wi-Fi settings and look for the network named “GTA San Andreas Clock” (or “WLED-AP”). Connect to it using the default password: wled1234.

3. Link Your Home Wi-Fi: Once connected, a configuration page will automatically pop up on your screen. Tap WiFi Settings, enter your home Wi-Fi network name (SSID) and password, and click Save & Connect.

4. Launch & Control: Reconnect your smartphone to your normal home Wi-Fi and open the WLED app. Tap the + icon in the top right corner and hit Discover Lights—your LED clock will instantly appear, ready for you to customize its colors, brightness, and retro lighting effects!
