Manta Ray Flexi

Flexi Manta Ray — Articulated Desk Toy

Important: This model was developed and tested on Bambu Lab printers.
If you are using another printer or slicer, please make sure your machine is calibrated and settings are tuned correctly.
I can’t guarantee identical results on every third-party setup.
Please rate the model based on the design itself, not issues caused by printer calibration, slicer settings, or hardware limitations.

Cute articulated manta ray printed as a single piece with no assembly required.
Thanks to the segmented flexi design, the wings and tail move smoothly, making it a fun fidget toy as well as a decorative desk figure.

The model is optimized for FDM 3D printing and prints without supports.
Works great with PLA+, PLA Tough, or PETG.

No supports. No brim.
This is a print-in-place model designed to print 100% without supports or brim.
Adding them will actually break flexibility and cause issues.

Recommended Filament

For best durability this flexi toy is recommended to be printed with PLA+, PLA HF, PLA Tough+ or PETG.
Standard PLA can be more brittle and may break if the joints are forced.

Tested with Bambu Lab PLA Touch+ and holds up well during regular play.

Important
This model is designed as a decorative flexi toy. The joints move freely but should not be forced beyond their natural range.

The eyes are designed as a tight press-fit, so no glue is required 🙂

To install them, gently press them in using the handle of a tool (for example, a support removal tool) — this gives better control and prevents damage.

If needed, you can slightly warm the part in your hands or scale the model up by 1–2% for easier insertion.

The fit is intentionally tight to ensure the eyes stay in place without glue.

Perfect for:

• desk decoration
• stress-relief / fidget toy
• gifts for kids and adults
• marine animal collections
