Echoes of strategies throughout the eons challenge you to epic duels.
A two-player race strategy game played at least since five thousand years ago. The first boards were discovered at the Royal Cemetery of Ur in 1922 (this is where the game got its name from) and the rules were deciphered several decades later from Babylonian clay tablets.
The board pattern design closely follows the specimen pictured here:
and is optimized for a 0.45 mm perimeter width.
A modular board design helps with capturing the fine details of original design, as larger individual tiles can be separately printed even on smaller beds; additionally, the tiles can be easily stored.
Each player takes a set of seven pieces. Every piece must enter and exit from the board at specified locations. The first player to move all their pieces off the board wins.
At each turn a player rolls a set of four tetrahedral dice to determine the number of squares a piece can move. Each die has two marked sides*, corresponding to 1, and two unmarked sides, corresponding to 0, so each roll yields a number between zero and 4.
When a player rolls the dice, they have the following options, of which they must choose only one: introduce a new piece on the board, move a piece already on the board along its path, or move a piece off the board. Note that a piece can exit the board only if the player rolls the exact number that would bring it off the board (number of remaining squares + 1). If no move can be made, the player loses their turn.
Every square can only be occupied by a single piece. A player cannot place multiple pieces on the same square. However, a player can move their piece to a square occupied by an opponent’s piece: in that case, the opponent’s piece is ‘captured’, i.e. it is removed from the board and must start anew.
Rosette squares (the flower shape) are special: when a player moves a piece to this type of square, they get an extra turn. Moreover, pieces on rosettes are safe from capture; an enemy piece cannot move to an already occupied rosette.
There are two possible game paths, and which one is used must be agreed upon before the game begins.

*The original game calls for tetrahedral dice with two of the corners of each die bearing colour markings. This would not work on a single nozzle printer, so we opted for truncated tetrahedra with slight insets on two of their triangular faces.
Materials and methods
Everything prints at 0.2 mm layer height.
Set your line width to 0.45 mm, as the pattern design is optimized for it.
Bridge settings must be on.
The board, its border, and its patterns are provided as separate models, so that everything prints in your favourite colour palette. The same goes for the piece and its pattern.
Import the board into your slicer and then import the corresponding border and pattern as parts.
Use the same procedure for the piece base and its pattern.
The board and the piece base are 3 mm high, while the board border, the board pattern, and the piece pattern are 0.4 mm high. When using a single nozzle printer, you can issue a colour change command at the 3.20 mm mark to switch to a new colour.
Issues are used to track todos, bugs or requests. To get started, you could create an issue.
I'm so excited to find this, but I've never printed anything with layers like this. When I group them on the Cura table, it seems to group them upside down. Any hints on that? Plus, I can enable bridging, but are there any particular settings with that I need to be sure of. Thanks so much for any response.
