Enneagrammic Antiprism (9/5)

The Enneagrammic 9/5-Antiprism: A Shape Beyond My Previous Creations. This shape is significantly more complex than my earlier 9/4 antiprism, resulting in a unique design where the top and bottom 'star' sections are connected by a thin rod, with the tip of the star meeting at a single point. To ensure structural integrity, I've added thin circular reinforcements to these delicate edges, as seen in the stl file. Without these reinforcements, the shape would be prone to breaking. My successful print was achieved using a scaled Z height of 40mm and 1.5mm layer thickness with PLA material. At these settings, my reinforcement rods are not visible, yet the shape holds together remarkably well. During the CAD design process, I encountered some interior holes that might be detected by your slicer. Rest assured, these imperfections do not affect the exterior of the print. I'll upload a revised version to address this issue. To ensure a successful print, it's recommended to use rafts unless you're confident in your printer's ability to prevent lifting.
