I've been wanting to make this type of series of hooks for a long time, so I'm just using this as an excuse to try another one.2017 Rhino https://youtu.be/FvZzgyoLI-Q , later changed to 3D printable hooks https://www.cgtrader.com/products/rhino-hook .

This model is suitable for either hot melt 3D printing or light-curing 3D printing, and it is recommended that the print size should not exceed 12cm in length.
