# Current Challenge: July 2026

## Challenge: Scarf Seams

Master the art of scarf seam placement! This month's challenge focuses 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 asks you to create a model with a carefully placed scarf seam on a **sphere**. Use this opportunity to experiment with different settings and share what you've 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:
