Orbloom – Echo Dot 4 & 5 TPU Cradle

An organic cradle designed for Echo Dot Gen 4 & 5 — printed entirely in flexible TPU.

No supports required

Orbloom wraps around the speaker like a living symbiote, creating a unique floating look while keeping the device secure, stable, and fully functional. The flexible structure allows effortless insertion and removal without forcing or scratching the Echo Dot, while naturally adapting to small tolerances between printers and materials.

Printing Instructions

The included print profile is highly recommended for best results.]

Orbloom was primarily designed and tested for Bambu Lab TPU for AMS, but standard TPU 95A also work very well. Softer shore hardness materials will probably work too, but they have not been tested yet.

For optimal surface quality and flexibility, I recommend using:

• Arachne wall generator
• 3 walls
• 5% Gyroid infill
• Activate FuzzySkin
  • Point Distance: 0.05 mm
  • Skin Thickness: 0.05 mm

Because TPU tends to produce smooth and reflective surfaces, I used a very subtle Fuzzy Skin texture to create a more organic premium finish while helping hide visible layer lines.

This is an extremely subtle texture — just enough to create soft reflections and a much more refined final appearance without making the surface look rough.

Assembly

Simply align the Echo Dot using the “BACK” marking inside the base to ensure proper cable routing and speaker orientation.

The TPU structure is designed to flex naturally during insertion, allowing the Echo Dot to slide into place smoothly and securely with almost no effort. Once inserted, the material gently grips the speaker while keeping full access to the cable opening and maintaining proper sound projection.

This model was specifically engineered for flexible TPU materials. Printing it in rigid materials such as PLA or PETG is not recommended and may result in part failure or breakage during assembly.

Description

Orbloom is an organic TPU cradle designed for Echo Dot Gen 4 & 5, inspired by living roots, alien organisms, symbiotic creatures, and dark sci-fi aesthetics.

Instead of looking like a traditional stand or generic 3D printed holder, Orbloom was designed to feel like a living structure wrapping itself naturally around the speaker. The flowing organic shapes create the illusion that the Echo Dot is floating inside a soft alien entity while remaining fully stable and functional.

The flexible TPU body allows the speaker to slide smoothly into place without clips, screws, magnets, or rigid locking mechanisms. The material naturally deforms during insertion and adapts around the Echo Dot, creating a soft but secure grip that feels surprisingly natural in use.

The open structure was carefully designed to preserve the visual presence of the Echo Dot while maintaining proper cable routing and unobstructed sound projection. The internal “BACK” marking helps identify the correct orientation for installation and cable placement.

Orbloom was heavily optimized for FDM printing and specifically engineered around TPU behavior. The thick organic walls provide enough structural rigidity to support the speaker securely while preserving the flexibility required for effortless assembly and removal.

The subtle fuzzy texture used in the print profile transforms the surface appearance completely, creating a soft organic reflection that resembles molded silicone, alien skin, or cinematic creature props rather than a typical layer-based 3D print.

Depending on the filament color, Orbloom can completely change personality:
black TPU creates a stealthy symbiotic look, translucent materials produce glowing sci-fi effects, while toxic green or colored TPU variants can create strong alien, horror, biomechanical, or organic creature aesthetics.

The design takes inspiration from organic roots, symbiotic growth, sci-fi horror visuals, dark fantasy environments, biomechanical creatures, and flowing natural structures. Some users may even recognize visual influences reminiscent of alien organisms, living vines, parasitic entities, or cinematic symbiote aesthetics.

Despite its sculptural appearance, the model remains practical, easy to print, compact, and highly functional for everyday desk setups, gaming spaces, streaming environments, bedrooms, offices, and modern minimalist setups.

Orbloom works especially well in low-light environments where the Echo Dot glow interacts with the surrounding organic structure, creating a subtle atmospheric lighting effect that changes depending on the room and filament used.
