This model has not been extensively tested and its durability is unknown! Using it may result in serious consequences, so proceed with caution! To achieve optimal results, print at a relatively high resolution to prevent deformation caused by separation of layers. If you do decide to print this, please let me know the outcome! I used Blender with Bezier curves to create this design, and have made the file available for anyone who wants to modify or repurpose it.
