+# Past Challenge: September 2026
+
+## Challenge: Practi"FALL" Prints
+
+As we headed into fall, it was time to show off the practical power of 3D printing with **Practi"FALL" Prints**! 
+
+Whether it was an everyday household fix or a clever workshop tool, makers brought in practical prints that solved problems or made life easier.
+
+### The Focus: Functional Utility & Everyday Practicality
+The goal was to design or print a functional item that serves a practical purpose. This could be anything from a simple door stop, cord clip, or drawer organizer, to a crazy multi-levered bottle or can opener, tool jig, or replacement bracket!
+
+### Submission Requirements
+
+* **Physical Model**: Brought to the **September 16th, 2026** meetup.
+* **Range of Entries**: Anything functional qualified—from simple everyday utility items to complex mechanical openers or tools.
+* **The Story**: Participants demonstrated or explained what problem their print solved, how they used it, and their printing/design approach (materials, infill, orientation for strength, etc.).
+
+### Judging & Prize
+
+* **Voting**: The group voted on their favorite entry based on practical usefulness, creativity, and execution.
+* **Prize**: The winner received a **free spool of filament**!
+
+### Timeline
+
+* **Challenge Announcement**: August 19th, 2026 (at August meetup)
+* **Show & Tell / Voting**: September 16th, 2026 (during September meetup)
+* **Winner Announcement**: September 16th, 2026 (end of September meetup)
