Figurine in a dice

Balanced dices

Dices are balanced, figurine's center of gravity is put in the center of the dice.

If you want to keep the dice balance, print it with 100% of infill.

If you want to create another read the part: "how I made them"

Don't forget to post a make.

how I made them

Copy model to animals/heart_gem.stl

Install numpy-stl if needed

pip install numpy-stl

launch the "center of gravity" script with the model as parameter

python get_center_of_gravity.py animals/heart_gem.stl

Output of the script:

Volume                            = 117.31810242698218
Position of the center of gravity = [3.84325029e-03 1.01203855e+00 1.12715415e+01]

add it in the code, in the module animal() duplicate an animal line 95

    else if (animalName == "fox") {
        animalModel(file = "animals/foxLowPoly.stl", scalePercent = 1, centerOfGravity = [- 14.18385003, 4.57492739, 75.20926315]);
    }

change file and centerOfGravity

    else if (animalName == "heart_gem") {
        animalModel(file = "animals/heart_gem.stl", scalePercent = 1, centerOfGravity = [3.84325029e-03, 1.01203855e+00, 1.12715415e+01]);
    }

in line 2 add heart_gem

part = "fox"; // [fox, dino, dragon, cat, panda, heart_gem]

Open the file dice_animal.scad in openscad and choose in the customizer animal : heart_gem

Change the variable scalePercent so the model fit inside the dice. (Note: check every faces)

For the heart_gem, the model is upside down, so I add rotation = [180, 0, 0]

The final code is:

animalModel(file = "animals/heart_gem.stl", scalePercent = 0.7, centerOfGravity = [3.84325029e-03, 1.01203855e+00, 1.12715415e+01], rotation = [180, 0, 0]);

See every changes for adding this model in this commit 5f048454d40d1761096770d57f2074d0c837404c

Render the model to check if everything is ok.

Print it with 100% of infill to keep the dice balanced.
