I designed this record-keeping dice tray for
Chain of Command in Blender, and it's printed now in PLA at 0.2mm layers. It took about 24 hours all up, for the tray, pegs and morale dice, so not an insignificant print job.
On the left, and turning a corner to run across the top, is the Morale Track. In this instance, the force has 11 morale, one peg for each level of morale. Immediately below the last five morale pegs are recesses for dice indicating the effect of falling below that level of morale: loss of a Command Die (the 5-spot icon), loss of a Jump-Off Point (the letter J), or loss of a special Red Command Die (the red square).
Immediately below that is the rack for the command dice, designed to accommodate up to eight 12mm dice (though most forces will only need five). In this instance, there are five regular command dice and one special red die.
To the right of the Morale track is the Chain of Command track. Every time a five is rolled on a Command Die, a red peg is added to the CoC track. When six fives have been rolled, add a gold Chain of Command peg and remove all the red pegs from their holes — there is space for up to three CoC pegs, though it's unlikely that anyone would collect that many before using any.
To the right of the CoC track is a cavity to keep CoC pegs and any other spare bits and pieces in.
And at the bottom, of course, is the dice tray itself. I ended up covering the bottom with a thin sheet of self-adhesive closed-cell foam to cut down on the clatter.
All in all, I'm pretty happy with it.
