Bambu Lab Spool – 99% original match !!! (+Screw)

Bambu Lab Filament Spool – Ultra Accurate Model

We modeled it to the same level as the real thing through precise 3D scanning and reverse engineering.

📌Download the attached 3D CAD STP modeling and use it for new product development.

• Original Modeling: It is not intended for 3D printing purposes because it is identical to the real thing.
• V3: Minimal Modification Version for 3D Printing (🔄 Update 2026-04-27)
• 🔩Screw lock type: Easy assembly, strong fixation. (✨New !)
• Blind hole version for high-speed printing 🕓 (✨New !)

A highly accurate digital replica of the Bambu Lab filament spool, carefully modeled to match the real product.

Designed for makers who need real-world dimensions for design, testing, and prototyping.

Accuracy: 99% identical to the original

Perfect for:

• Spool holder development
• Perfectly compatible with AMS 1, AMS 2 Pro, and AMS-HT
  • (It is also compatible with all dryers that use Bambu Lab Spools.)
• Filament storage system design
• Product mockups and simulations

Model Features

• Real-scale dimensions
• Clean and optimized geometry
• Ready for CAD reference and prototyping

Built for engineers, designers, and makers who want reliable real-world reference data.

※ Differences from the original (for smooth printing)

① Removal of overhang rounding

② Removal of injection draft angle

※ Note

① Self-release when Cooled Down

: PEI is an excellent material for 3D printing applications due to its ability to withstand the repeated heating and cooling cycles of a printer heatbed. Prints come off easily when the temperature of the heatbed reaches room temperature, and we always recommend waiting until it reaches 35℃ or lower. If the print is still adheres to the plate, simply bend the steel plate and the model will fall right into your hands.

② When assembling with an existing spool, it may feel slightly stiff. This is an intentional design feature, and it will become smoother with use.

③ When drying filament, You must use at least PETG. (If drying is not required, PLA is also fine.)

④ If using AMS-HT or a high-temperature dryer, use ABS.

⑥ Printout size

: All holes are modeled to be the same size as the actual size or slightly larger. However, shrinkage may occur in the printed output. Therefore, if you require precise hole sizes, drilling may be necessary. This is optional.
