This model measures 196 × 67 mm with an inner hole diameter of 55 mm. It is designed to fit spools with an 83 mm paper core, such as those from Anycubic. Styled to resemble the Bambu Lab spool, it has been adapted to match the positioning of stickers and NFC tags found on Anycubic refill spools. By aligning the slots and twisting to lock, it integrates securely with the ACE Pro multi-color filament system, ensuring smooth filament feeding and quick swaps.

For best results, print the model using a heat-resistant material such as PETG or ABS.
