Designing a Functional 3D Printed Crossbow | Mechanical Engineering Breakdown

We created a compact, durable crossbow mechanism that stores real energy, releases reliably, prints without supports, and assembles cleanly using only printed parts. In this video, we walk through the mechanical design decisions behind the limbs, trigger, shuttle, and adjustable stand — including early stability issues, binding during cocking, print orientation challenges, and how we refined the geometry to improve strength, alignment, and reliability. You’ll see: ✔️ How the flexible limbs store and release energy ✔️ Why early carriage designs caused lifting and binding ✔️ How gravity-based trigger geometry enables reliable engagement ✔️ Print orientation strategies for strength and smooth motion ✔️ How pivots, snap fits, and controlled flexure work in real prints ✔️ Launching both printed arrows and Nerf darts This design prints in multiple parts using standard PLA and assembles without hardware or glue. All components are optimized for strength, durability, and smooth mechanical motion. 🎁 Free STL Files for Makers: MakerWorld: https://makerworld.com/en/models/2299...
