This is a precision-designed spacer for Bambu Lab refill spools, created to eliminate filament tangling and AMS feeding issues.Boost MeIf you like this model, please Boost Me for free!If you've used refill filaments, you’ve likely encountered a common problem — gaps between the filament and the spool can cause the filament to slip, bind, or get trapped during rotation inside the AMS unit. This often results in frustrating interruptions like "AMS Overload" or failed prints. Unlike other spacer designs available, this model has been carefully developed through extensive prototyping, real-world testing, and research. The goal was not just to reduce the issue, but to eliminate it reliably. The spacer fills the critical gap and stabilizes the filament roll, preventing it from slipping off the spool edge or getting wedged between layers. This ensures smooth, consistent feeding throughout the entire print — even on long jobs. Key Features:Prevents filament tangling and AMS overloa
