I made those solids for my old highschool teacher who needed them for her math's lessons and now I'm sharing them with you:)
Size:
-Every edge of the base is 15cm; Everything fits on Prusa MINI.
Printer/Filament + Printer settings:
-Prusa MINI with Prusament PLA with default 0.2mm Prusa MINI settings.
Infill:
-15%-100% (40% worked just fine for me without extending the printing time too much)
Supports:
-Required custom supports for greem triangle in pyramid1,
-Can print without support but it's risky (1/4 prints failed). I recommend adding custom support just so the side edges don't wobble (it's fine 'til 3/4 of it's height).
*consider reducing the speed when printing without support (fixed the wobble problem in my case)
