Enneagrammic Antiprism (9/5)

thingiverse

The Enneagrammic 9/5-Antiprism. More complex shape than my 9/4 antiprism - due to this the top and bottom 'star' sections are technically connected by a thin rod only and the tip of the star (in the interior) meets at a single point. I have added some thin circular reinforcements to these thin edges as is seen in the stl. If they weren't present the shape would not print. My print was achieved at a scaled Z height of 40mm with 1.5mm layer (PLA) - at these settings my reinforcement rods are not visible - but the shape holds together. For some reason in making the CAD for this, there seems to be some interior holes in the design that your slicer may pick up on - these do not affect the outside of the print so do not worry. I will try to upload a fixed version. Print with rafts unless you are certain your print won't lift.
