King Dice... dice containter! (Cuphead)

This was designed for the “Dice Container” contest, which I took as a challenge to learn/improve CAD skills. At its core, it is a simple dice-shaped box, with magnets used to keep the top cover in place. Its dimensions allow to store a total of 216(*) 16mm cubic dices. The 1-face is decorated with the face of King Dice from the game Cuphead.

(*) The number of dices is not casual. Remember who's the final boss of the game? ;)

Model Customization

Updating the Dice

I am planning to update the design file so that people can play with it easily - to change magnet size and whatnot. I have to fix a couple of things, once done I will explain how to customize the dice model from Fusion 360 :)

Changing facial features

In the “Other Files” section, you will find “face.svg”: it's a drawing, created in Inkscape, containing all facial features (eyes, mouth, mustaches, …) that can be added to the container. Edit it as you please, just make sure that all objects in the final design are closed paths - otherwise, extrusions will not be possible later on. Once you are done with your changes, select from the main menu bar “File/Save a Copy…” (or use SHIFT+CTRL+ALT+S) and in the file type choose “Plain SVG”. This is VERY important: Fusion 360 has sometimes issues reading Inkscape's SVG flavor. Give a name to the copy, e.g., “face-plain.svg”, and save it.

Open the CAD file “KingDice.f3d” in Fusion 360 and select the face with a single dot. Right click on it, and choose “Create Sketch”. On the top bar, look for the “Insert” button, click on the drop-down menu and choose “Insert SVG”. Select the plain SVG file you exported moments ago. Move and resize as needed, then click on “OK” on the “Insert SVG” dialog. Check that the imported shapes are all closed by hovering on them. If that is not the case, you may want to go back to Inkscape and fix the drawing. Otherwise, click on “Finish Drawing” and then press “E” to start extruding. Select the inside of the drawn shapes, then choose the thickness of your liking ("Distance" in the dialog) - personally, I settled for 1mm. Make sure that the operation is set to “New Component”, then confirm.

PS: The drawing was my first “serious” attempt at digital art, and, while the result exceeded my expectations, I think it looks a bit off. If anyone wants to try doing a better job, please do! And if you don't mind, please share the updated SVG in your makes. With your permission, I will add different variants to the model so that people can choose between different expressions.

Making the King

For the main container and the cover, I used Cura as slicer. I started from the “low quality preset” (0.28mm layers) and changed the following:

• Infill: I reduced the density to 7.5% to save some material and chose the Zig Zag pattern. The main concern one should care about is that the base layer for the magnet sockets need some support lines below them - with some other densities and patterns, I had Cura trying to print circles mid-air.
• Supports: they should be enabled, with the overhang angle set to 46deg. The only parts that will need support with these settings are the dots of the bottom face and some portions of the lower fillets. The dots in the lateral faces of the cube were designed so that they form at most a 45deg overhang angle, removing the need for supports there.

Note that the cover will need to be rotated upside-down right after importing it in Cura, so that the face with the dots lays down on the plate.

To get a better-looking finish, I recommend sanding and coating with filler primer before coloring with white & violet. Glue little magnets (5mm diameter, 2.8mm height) inside the cavities of both the cover and the container.

To print the eyes, mouth, etc. my recommendation is to use Cura's standard quality profile (0.2mm layers) with the “Ironing” option enabled. I recommend to slice different parts separately: the lines are quite thin and the printer might have troubles doing a clean job. By printing all facial features separately, one can stop the printer when one part fails without having to “sacrifice” the rest. Glue the printed parts on the dice and you're done!
