This bigger version fits some slightly larger but common 7-piece dice sets. See my previous remix (based on 3DCentralVA's and the same size as that one) for other changes.
Printing tips:
Tray: The version of the tray marked "support-free" may droop with inadequate cooling, a low quality setting, or other factors. Considering that, maybe just go with the "square ends" version since it fits the aesthetic better, and use supports.
I recommend using the included supports (use your slicer's join feature to align them) which seem to work better than PrusaSlicer's or Cura's, probably because of the steep angle,
Tower: support-free
Brick pattern: For the photo, I used my PrusaSlicer fork which has the ability to use a displacement map: https://github.com/prusa3d/PrusaSlicer/issues/8649 (The issue links to the brick bump map itself which is also required). Doing the displacement during slicing uses up much less storage for the model and is less taxing on your 3D model preview in slicer or Blender etc, and allows for far easier editing later at least vs applying a displacement though you can keep it not applied in Blender if you do it there (but the STL will still be large and taxing on your slicer and internet if uploaded/downloaded).
Painting:
Use adequate ventillation and PPE as recommended by the usage instructions of the products. See license for disclaimer.
Plastic primer
ModPodge (to hide layer lines)
Another coat of plastic primer (since paint wouldn't stick to glossy ModPodge. If using a high quality slicer profile it may take over 12 hrs to print on some printers & profiles but you can skip steps 2-3)
Paint with base color (then blow dry)
wash (watered down dark color, then blow-dry again)
Dry-brush with base color with natural sponge (and paint some lines in a brick pattern for fake stones on flat areas)
Dry-brush highlights
Dry brush even lighter color with detailing strokes (on actual raised areas and parts of faked stones facing imaginary light source).
