Edit: Shell Presto asked if they were resin or filament. Good question. I printed the dice in resin, I aligned them at 45 degrees, and used small auto supports.

Dice on the tray:
Trader’s Galaxy recently released sets of their custom dice for playing games like BotWar and Rise of the Democracy. I did a quick review of the tribe for April of 2025 here.
I typically shy away from games that have custom dice. I don’t want to have to buy tons of dice for games. I never got into Star Wars Legion for this exact reason. The game looks fun, but the starter sets don’t come with enough die to actually play a full game with. Give me some d10s and d6’s and let me have fun.
So I decided to do an experiment and see if the die were fair. I rolled everything through a dice tower, and then recorded the results. I rolled 145 times.
I used the Chi-squared method to see how well they rolled.
For those who are not 3 classes shy of a mathematics degree like me, the Chi-squared method is a statistical analysis. You take the sum of all the results with the square of the Outcome - Expected result squared divided by the expected results.
Which leaves us with x squared = 1.10. The common threshold for signifcance is x squared = 5.99.
So in conclusion, my 3d printed dice are very fair. Therefore I have no problem using them in a game.
Interesting experiment and analysis! You won't find that in many other gaming magazines.
But my question to you is: who wants fair dice?
I've had plenty of "manufactured" (i.e. store-bought) dice that weren't fair. I still have the first d20 I ever owned (it came with the original Blue Box DnD Basic Set) and it was so notoriously unfair I had DMs who wouldn't let me use it (it rolled 20s about 15-20% of the time).😂
