+### Challenge Reminder: Bring an Experiment (Round 2!)
+
+Don't forget to bring your **Bring an Experiment** entries for judging! Due to popular demand, we ran Round 2. We challenged you to try something new, crazy, or wild. Bring in your experiments—even if they are completely failed prints (we love spaghetti!). Be prepared to share what you tried, why you tried it, and whether it worked. We'll vote for the favorite experimental attempt, and the winner gets a **free spool of filament**! 
+
+### Special Topic: Introduction to CAD
+
+This month's special guest topic is an **"Introduction to CAD"** presented by **Tom**, one of our community members and the creator of [Orbit Panels](https://orbitpanels.com/). If you've ever wanted to design your own parts or take your 3D printing capabilities to the next level by creating your own 3D models from scratch, this is the session you won't want to miss. 
+
+See you there!
