I put something with 500 lbs on it, and it just broke -_-..

well make sure you're going by Mass which is Kilograms and also make sure you're not looking at Density which is mass over volume. You very well could've put a large block with 500Kg/m2 which would be too much if your block was any larger than a 1x1 square. It's best to just use the shapes provided so that there's no chance you'll go over your limit.

lol, paradigm u no all the stuff u created except for this, it doesnt stop at 900kg/m2
it goes to 1000kg/m2

dont get mad (not that u r) i wasnt like doing a "braggy" thing
im not THAT stupid, though i am stupid from time to time, arent we all

Nice! What font is that?

I don't even know really. I just remember Phunletting a whole bunch of letters and numbers a long time ago.

if u ever have the time, u should use that as suspension so that u could measure the pressure being put on the springs
