Halloween Crypt Lantern – Coffin Glow Edition

Summary:

Bring some eerie ambiance to your Halloween display with this glowing crypt lantern! The design features twelve coffin-shaped stained glass windows surrounding a flickering candlelit interior, capped with three raised coffins on the lid.

Each window insert is printed separately to reduce filament switching — simply use translucent orange PETG for the window panels and gray PETG for the stonework. Add a few LED tealights inside, and your crypt will come alive with an ominous, pumpkin-orange glow.

Insert the windows.

Slide each window panel into the slots around the crypt body.

They should press-fit snugly — no glue required.

Add lighting.

Place 3 LED tealights inside the crypt base.

Do not use real candles (heat will damage the print).

Align the coffins with the window panels and set the lid on top.

It can rest loosely or be glued if you prefer a permanent seal.

Turn off the lights and enjoy the eerie orange flicker through your glowing Halloween crypt!

💡 Tips & Variations

Use color-changing LEDs for an extra-creepy effect.

Print the coffins in glow-in-the-dark filament for nighttime ambiance.

Scale down for miniature tabletop decorations or up for porch-light displays.

Add a light diffuser sheet behind the inserts for an even softer glow.
