A dust filtering sieve tray designed for tofu cat litter and mixed cat litter.

This model uses a material-saving slot pattern instead of traditional honeycomb or dense round-hole designs, significantly reducing print time and filament usage while still maintaining effective dust filtering performance.

The slot spacing has been optimized for common tofu cat litter pellets, helping quickly separate dust and small debris while minimizing usable litter waste and improving daily cleaning efficiency.

The model features a flat-bottom, support-free design that prints easily on standard FDM printers and works well with common materials such as PLA and PETG.
