This is a 3D-printed rear harness buckle made for any Cap costume, modeled after the final-era uniform from the later missions. It’s a great way to add that realistic, battle-ready look to your setup.

Printed in silver PLA plastic with durability in mind, this buckle is designed to work with functional strap setups and hold its shape during wear.

📏 Measurements:

  • 6" wide x 5.2" tall x 0.27" thick

  • Fits 2" wide straps on top and 1.6" wide straps on bottom

You can paint it if you want, but honestly — it looks sharp right off the printer.

⚠️ This is a decorative costume piece and may break with enough force. Please handle with care during install and use.

📦 Ships FAST via USPS anywhere in the U.S. 🌍International customers - please see our eBay store for overseas shipping!

🔥 Heat Warning: PLA plastic softens at temperatures above 150°F. Clean using soap and lukewarm water only.

This is a 3D-printed item, and due to the nature of the process, minor blemishes, layer lines, or sharp edges may occur. These can typically be smoothed using a heat gun or hair dryer and light pressure.

We aim for a high standard of quality on every piece. If anything arrives less than perfect, reach out — we’ll make it right.

Fantastic piece! Better appearance and quality than I expected. The slots were the straps attach seem durable and don't seem easily breakable. Hoping to rig up a hook on it to hold the shield.

Sturdy and looks great. I'm going to paint it silver so it matches the rest of costume, but if you don't already have hardware to match it doesn't even really need to be painted.
