As the title says I propose adding equilateral triangle pieces, in other words triangle foundation pieces where all three sides are the length of the side of a standard foundation square. While we do already have the 90° triangle pieces, which work well enough for most situations, the limitations of this piece in that you cannot snap fences to it or have a window/door in that spot severely limit design opportunities in my opinion. Having an equilateral triangle, similar to games like Rust or ARK, along with the 90° would add far more options and allow players to build even grander designs for their bases. This new piece would allow for angled railings, doorways, windows and a more circular layout for bases to better fill out the Palbox build radius while also allowing square or 90° triangles to snap to all three sides.

In short I am suggesting the addition of a 30° equilateral triangle foundation, ceiling and roof piece that has the same side length of a standard square foundation for more build options. Attached is a pair of example images for how to use the proposed 30° triangle piece
