Advent Calendar Stained Glass Window Inserts

✨ Nativity Stained-Glass Cathedral Window Set – Interchangeable LED Display

Bring the story of Christmas to light with this stunning 3D-printed stained-glass Nativity window collection, designed to fit perfectly into my modular cathedrals, towers or other illuminated displays. Each window tells a piece of the Christmas story — from the shepherds and wise men to the Holy Family — in vivid, jewel-like color.

There are so many different windows and building options that I have opted to make different models for each one instead of making a ton of print profiles that are very difficult to navigate. This will make it much easier to print from a phone as well. Please access the various models here:

Stackable Tower with interchangeable Stained Glass

Create a glowing Advent display with interchangeable 3D-printed Nativity windows that swap easily and print efficiently with just one AMS unit.

🌟 Features

• Over 33 interchangeable stained-glass panels depicting the full Nativity scene to choose from
  (Mary, Joseph, Baby Jesus, shepherds, angels, wise men, animals, and stars)
• Printed separately for easy swapping — you can print each window in its own color combination and switch them out without reprinting the tower
• Saves on filament changes — only requires one AMS unit or even a single-color printer setup
• Works with LED tealights or lamp kits — the translucent filament glows beautifully when lit from within
• Compatible with my modular cathedral tower system (fits 6 mm deep × 30 mm wide × 53 mm tall window slots)
• Magnet-ready inserts for quick window swapping — ideal for seasonal changes or use as an Advent calendar
• Two styles included: arched cathedral windows and round rose-style designs
• Beautiful whether lit or unlit — crisp black linework and translucent color layers give an authentic stained-glass look

🕯️ Suggested Uses

• Advent calendar: reveal one new window each day leading up to Christmas
• Holiday décor: create a glowing tabletop cathedral, chapel, or nativity lantern
• Educational or faith projects: visualize the Nativity story in a creative 3D format

🖨️ Print Recommendations

• Material: translucent PLA for the glass sections, black or metallic filament for outlines
• Lighting: LED tealight or LED lamp base (do not use open flame)
• Optional: insert small magnets to make the windows easily removable and interchangeable

🎁 Maker’s Note

This set was inspired by classic cathedral stained glass — each window was drawn and printed to balance color, light, and story. When illuminated, the windows transform into glowing miniatures that fill any space with warmth and wonder.

If you enjoy this design, please boost ❤️ and share your printed versions — I love seeing how others integrate the windows into their own towers, nativity scenes, and seasonal displays!
