Strainer/Sifter Bowl (3 Hole Sizes)

Three versions included — pick your hole size: 2.5 mm / 3.5 mm / 5.0 mm
Simple multi-purpose strainer/sifter bowl with a pour spout and side handles. I originally made this to separate milled bird seed from pellets/whole seed so I can keep more of the good stuff (less waste) and dump it back into the bowl cleanly — but it also works great for sorting/sifting small parts and materials.

Choose your version (hole size)

• 2.5 mm holes — finest sift
• 3.5 mm holes — medium sift
• 5.0 mm holes — coarse sift

Features

• Pour spout (~40 mm wide) for controlled dumping
• Dense sift field for fast draining/sifting
• Side handles for easy grip
• Rounded edges for comfort

Great for

• Bird seed sorting (milled vs pellets/whole seed)
• Small hardware / screws / washers (shake out debris, rinse, dry)
• Tumbling media separation (hobby use)
• Beach sand / sea-shell sorting
• Shop / garage cleanup (sorting small parts)

Print notes

• Prints support-free (supports not required)
• PLA works fine for general use; PETG is tougher for shop/utility use

Files included: 2.5 mm / 3.5 mm / 5.0 mm versions (3MF/STL)
