🛠 AMS Round Display Mod for Bambu Labs

Bring intelligence to your Bambu Labs AMS with this embedded environmental display mod. Designed by Gary Erwin (aka Captain Shank), this sleek upgrade integrates a 240×240 round TFT screen and a temperature/humidity sensor right into your AMS enclosure—giving you real-time visibility into internal conditions without opening the lid.

📦 What It Does

This mod reads and displays:

🌡 Temperature in Fahrenheit

💧 Humidity percentage

🛡 Chamber seal status (GOOD / SUSPECT based on humidity threshold)

⏱ Countdown timer until next sensor update (every 5 min)

All rendered in a clean, readable UI designed specifically for round displays mounted in tight spaces.
