Stranger Things Portal Globe – Upside down Display Diorama (Mindflayer / Demodog)

A glowing portal into another dimension — fully 3D printable, modular, and LED powered.

Bring the Upside Down to life with this fully 3D printable LED display globe, inspired by the iconic portal scenes from Stranger Things.

This project is designed as a modular diorama, allowing you to choose between two creatures:

• Mindflayer
• Demodog

Both versions use the same globe, base, diffuser, and cracked ground — simply swap the creature to change the entire look and mood.

🔴 Features

• Multi-part modular design – easy to print, assemble, and customize
• Low-profile cracked ground base – optimized for dramatic LED underlighting
• Cloud / fog diffuser – spreads the light evenly for an eerie glow
• Optional creature choice – Mindflayer or Demodog
• Designed for easy LED integration ( Bambu LED Lamp Kit )

💡 Lighting Effect

When illuminated from below, the cracked ground and fog diffuser create a deep red portal glow, bringing the creature to life inside the globe.
The result is a cinematic, atmospheric display piece perfect for desks, shelves, or collector displays.

🖨 Printing & Assembly

🎬 Final Result

This build captures the feeling of a portal opening into another dimension, with strong lighting, bold geometry, and a striking silhouette.

I spent weeks on blender creating and improving these models, I hope you enjoy them!

The assembly for the Globe I left open for now, so the ‘’creature'' can easily me switched out.

If you have any advice or points of improvement, let me know :)
