For those who want to try printing your own Coralok Disc, this is for you. Because of differences between 3D printing and injection molding, this model has been modified from the original Coralok Disc to get optimum printing results.
Notes: MUST BE PRINTED UPSIDE DOWN!!! with the grid pattern touching the printing bed. The grid is designed to take advantage of bridging artefacts and create a rough, glue-friendly surface. The actual pattern of the grid may or may not show up. Printing upside down is also important to keep the tabs straight.
