3D filament end clip with spring-back, AMS compatible, high-temperature resistant, for Bambu Lab filament spools

After getting the Bambu Lab P2S 3D Printer, filament storage became the biggest pain point: filament ends on the spool would run wild, not only affecting tidiness but also frequently detaching during high-speed rotation and high-temperature drying inside the AMS, leading to filament runout mid-print and directly ruining the entire print.

Having searched through various filament clip models within the Bambu Lab ecosystem, I tested 4-5 different types, and all of them had issues:

- Hard snap-on type: The structure would get stuck, impossible to operate with one hand, and difficult to attach or remove;

- Round hole type: The inner hole would deform after printing, unable to hold the filament, loosening with a pull;

- Regular material type: It would soften and deform as soon as it entered the AMS high-temperature environment, detaching directly and being completely non-durable.

Unable to tolerate repeatedly encountering these issues, I decided to model it myself. After multiple rounds of iterative testing, I finally perfected this exclusive filament clip with a spring-back structure, perfectly compatible with Bambu Lab AMS filament spools, solving all pain points at once:
✅ One-handed instant clip, zero operating threshold: Elastic buckle design, simply press and clip for easy fastening, no tools or effort required, can be attached and removed with one hand.
✅ No filament detachment at high temperatures, full AMS compatibility: Special spring-back structure + high-rigidity material, ensures no detachment or loosening during high-temperature baking and high-speed rotation inside the AMS.
✅ Optimized structure, zero printing failures: Redesigned buckle and inner hole structure, precise dimensions after printing, perfectly fits the filament spool, no warping or deformation.
✅ Material compatibility guide, maximizing durability:

- Regular filament: Recommended to print with ABS/ASA for a balance of toughness and heat resistance, stable and reliable for daily use.

- Carbon fiber filament: Recommended to print with PA6-CF and above filament, maintains high elasticity even after high-temperature drying, completely no deformation, zero wear and tear for long-term use.

Creation is not easy; every structural detail has undergone repeated testing and optimization. If this filament clip has helped you solve the problem of filament ends running wild in your AMS, please give it a 5-star rating to show your support. Thank you!
