FunDaMental Games has a print and play adventure well funded on Kickstarter for one player.
It’s a dice-themed game with dice monsters, dice heroes and dicey situations. To win? Tactics, points and dice. You can see and join from the pitch page.
The game uses a set of gamer dice, with special roles for d4 and d20. There have been parallels drawn with Yahtzee.
Unlike Yahtzee, there’s a set of STL models of the dice monsters and heroes to go with them.

You can support the crowdfunder by sharing it and offering cash. If you pledge CA$7, the digital file for Roll and Die will be rewarded.
Alternatively, CA$7 will secure you the STLs for six monsters.
Both? There’s a generous economies of scale, and CA$10, which is about £7, will get you those.
No 3d printer? CA$60, but limited to 200 people only and shipping on select countries, there’s a Die in the Dungeon board game. That’s a previous project from FunDaMental Games.
August 2022 is the estimated shipping date, even for the Die in the Dungeon board game.
