3D rendition of Ghee Beom Kim's 7-sided self-intersecting shape (2025-12-03)
I found the best quality was achieved by printing it vertically. Experimented with a few ways to split it and settled on chopping the “top” off. The 3MF includes:
Supports
2 different tops, one with a loop for hanging
Oblong for cutting locating pins out of
The body and top both have 1mm holes to help line them up while gluing. Clean the holes out with a 1mm drill bit, and then cut short (~2mm) segments of the oblong to go into the holes.
I have also included the complete unsplit HeptaPortal model if you wish to split it differently, or want to print it whole.
