+
+## Challenge: Scarf Seams
+
+Master the art of scarf seam placement! This month's challenge focused on dialing in your scarf seam settings and techniques.
+
+### The Focus
+
+The scarf seam is a powerful tool in your 3D printing arsenal. This challenge asked participants to create a model with a carefully placed scarf seam on a **sphere**. It provided an opportunity to experiment with different settings and share what was learned about getting the perfect seam placement.
+
+One of our community members designed a great test part specifically for this challenge! You can find their test model in our Discord server here:

+
+### Submission Requirements
+
+* **Physical Model**: Brought to the July 15th, 2026 meetup.

+* **Seam Location**: The seam was positioned on a sphere (the bottom half square approach was permitted).
