Those blueprint drawers are great for thiner light weight things. Mics and calipers, screwdrivers, blueprints/drawings, test meters/leads, etc...
Thick or tall and deep/wide as well.
Just shed one drawer, cut you a double-high-sheet-steel cover for the front of the one below the gap, grab the rattle-can.
Less work than trying to re-purpose the front salvaged off the pulled and asided drawer and easier to swap back if/as/when. Or hang the pulled one under yer benchtop. Big Box has ball-bearing slides.
Stiffeners can be added as well. The rails are good for it. Paper gets heavy enough, yah have much of it.
One-each double-height in my two stacks, they each seem four times as useful 'stead of part-time
aggravating.
Puttin' risers on the sides or a plywood box between so as to create an OPEN gap in between two stacked units, and stuff such as arbours for the horizontal mills, drawbars and such can have a new home for nearly free.
Or build that riser-box into the plywood reinforcement you needed under the bottom unit to attach
good caster wheels, anyway. Or both.
Side panel, optionally hinged "door" full height, each side, now your long rules, taller calipers, cordsets, hoses, and scraping dovetails have a safe place to hang.
Store-bought storage gear can be plumb lazy. Not sacred.
Gots to remind it who da BOSS now and then, yah wanna get useful WORK out of it.
