Aquascaping Grate

This is a support grate to be placed under hardscape in aquariums and to be covered by substrate. It helps to distribute pressure on the glas under heavy objects, raises the hardscape towards the substrates surface and prevents sinking into lose substrate like sand.
Advantage over conventional plastic grates often used in the hobby are the holes which allow circulation and root growth.

Easy to scale in your slicer, but for larger dimensions its better to multiply then to scale so that the lattice spacing wont change too much.
