This is an attempt at recreating the custom dice that supposedly shipped but no one got. While I took inspiration from the official dice, these are intentionally different so I don't have any legal problems. Feel free to remix and make them better.
Important You will likely need a resin printer to get these to come out nice. I'm waiting on mine and so these are untested. Print at your own risk.
03/26/18: Uploaded version 2 for all dice. These should be more uniform than the first version. I'll included a picture with my test print. I increased the size of the d4 and d12 after the print. Also messed with some settings I shouldn't have so they didn't come out as good as the first die. Considering them done unless someone chimes in with issues.
03/25/18: Redid the Core d6 in Blender and printed on my Anycubic Photon with default slicer settings and automatic supports:
Not sure what caused the lines on the second picture. I'll be redoing the rest of the dice and trying to dial in better settings before I call this done.
Anycubic Slicer Settings that worked for the first print:
Layer Thickness: 0.05
Normal Exposure Time: 8
Off Time: 1
Bottom Exposure Time: 50
Bottom Layers: 8
