new design time.

I think the problem lies with the green bogeys you have attached.  Would suggest picking them off.

Those bogeyes are the only part of the structure than can handle the stress

they are the restraints.

you are looking at product evaluation. the poor thing is under a load of 540kg (5400n force)

My Solidworks simulations never show up anything other than blue.

thats because your not making an efficient design   factor of safety of 3x lol for everyday items when you know the exact conditions of loading and the material.

Its allways efficent to not do a job properly.

does it need to have slanted sides?  the first one doesnt

if not... then the second one would be a lot stronger for a very small weight/cost increase with straight sides.

knighty, push the top of a square sidewards and it collapses easily, same for a pair, that shape doesnt. It trades squareness for rigidity.

Damn you screenshotting your damn cursor too. Had me wondering wtf was going on for a second.

dito, me too !

yeah... but with the force comming directly from above Is say that woulden;t matter

it would be a hello of a lot stronger with those straight sides

no because the parralellogram sides increase teh stiffness in the bar.

 you should see the rectangle bars i have really bust under this scenario.

theyll make it stiffer for twisting, but parallel sides will make it stronger against the force from above!

I assume this is made from an extrusion?

have you thought about putting fins inside the hollow to improve strength rather than changing the shape?
