About this 3D model

I wanted something to hold my chisels and didn't want to use a loose-fitting part since I don't want these falling on my workbench or my toes ? It took me a couple attempts to get the fit right and I've made the hex fit snuggly into an open holder spot. It also requires lifting the chisel about ½" before it can slide out. This way if I bump the wall I won't have sharp items falling.
