This is very entertaining… you’ll hate my methods of creating a printable triangular pyramid. It’s a bit rubbish but I know it works 100% for my needs. I can’t be arsed to do a YouTube thing, it’s so simple.
draw equilateral triangle… Shapr makes this super easy.
raise triangle by the calculated height of a pyramid.
scale top face to 1% twice.
I’d be amazed if you’ve got a printer that enables you to spot the tiny remanent top face!
Happy Xmas from a cheeky old fool…
