I present to you a stackable set of large 3D printed sieves designed for sorting pyrotechnic stars of various sizes. 

Features

- Multiple sizes ranging from 1mm to 14.0mm
- Stackable design allowing sorting with multiple sieves at once
- Embossed size indicators on each sieve for easy identification
- Perforated bottom allowing for accurate star sorting

Printing and Finishing

1. Print using a 0.6mm nozzle for optimal results
2. Lightly sand the inner top surface if it's rough after printing
3. Use a contrasting color marker or paint pen to highlight the embossed size indicator, being careful not to fill in the recessed areas

Usage Tips:

- The 3mm and 4mm sieves are particularly useful for starting rolled stars around mustard seeds
- When using, frequently sort out the larger stars to prevent clogging and ensure efficient sorting
