Built around your gear
Rack-ear switches and UPSes sit on support rails. Small PCs stand upright on shelves with cradles, laptops tent in grooved chocks, and a PDU or a $29 power strip hangs on the rear rails.
A 19-inch rack you print yourself.
Pick the height, depth and the gear that goes in each U. Layerack generates every part split to fit your printer bed, lays them out on print plates, and lists the hardware to buy.

Prints without supports
Every part is checked to fit your bed and print without supports. Long members split with bolted half-laps; the orientation for each part is picked for you.
Checked before you print
The configurator tests that parts don't collide, bolts only pass through holes, and cables clear the frame. A beam FEA estimates how much load each filament carries.
Everything on one list
Filament, bolts, nuts, dowels, casters, fans and cables, grouped with subtotals and links to buy them.
The load numbers are screening estimates, not a certified rating. Print a test joint, and load the rack gradually before trusting it with heavy gear.
