- Color Options: Available in Black, Earth Brown, and Forest Green. - Maintains Shape: Helps maintain the shape of the brace for storage. Printed in PETG-CF for better heat resistance than PLA. - Notched Design: The design has notches in the side so it doesn't interfere with the straps on the inside of the brace. This makes the insert slide in easier and prevents it from introducing wear onto the strap. - Thick and Sturdy: Printed with many walls for a sturdy print. As with all my products, if you have an issue let me know and I'll update the design and send a replacement! - Original, Innovative Design: 2000+ products designed and 3D printed in the heart of America in St Louis, Missouri by Hammy3DPrints.
