Diver spool with optional line guide

I've always wanted a spool with specific features that would make it incredibly versatile and practical. Firstly, I need a lightweight spool that's still remarkably strong, capable of holding at least 15 meters of robust, thick cord. The design should also allow the thumb to fit comfortably in the middle hole even when wearing a neoprene glove. This feature is essential for easy handling and manipulation of the spool. Another crucial aspect is compactness – the spool needs to be small enough to form a loop around it using the thumb and forefinger, making it convenient to carry or store. To achieve this design, I've utilized Autodesk Fusion 360, taking advantage of its parametric capabilities. By adjusting the h_spool parameter, you can modify the width (or height) of the spool to suit your needs. The provided photo showcases a 30 mm wide version with 13 meters of utility cord, which is approximately 3 mm thick. This design demonstrates the spool's ability to handle robust cords while maintaining its compact size. Assembling the spool is a straightforward process – simply screw the two halves together. If you prefer a more secure connection, you can print the parts from ABS and then dip the male thread in acetone for added stability. For those interested in the design details, I've made it available on A360: https://a360.co/2PaHuFT
