Round ESP32-C3 Holder with SSD1306 OLED Screen

A compact, round cylinder designed to house both an ESP32-C3 and a SSD1306 OLED screen. Perfect for small displays, desk projects, or Home Assistant integrations.

Features:

• Front display: The SSD1306 OLED fits snugly in the front, no screws needed.
• ESP placement: The ESP32-C3 slides in from the back and is secured with a small locking tab.
• USB-C access: The ESP’s USB-C port is accessible from the backside.
• Easy access: A round lid on top locks with two pegs and can also hold 6 × 2 mm magnets for extra security.
• Modular build: Print consists of 5 parts — base, lid, 2 pegs, and a locking tab.

Use case:
A great way to display live information, fun messages, or system stats. I’ve connected mine to Home Assistant to cycle through small info pages right on my desk.
