24U · 1000 mm · Freestanding · Mesh
A shared architecture for the 12U, 24U and 48U family. The 24U is the first engineering-development prototype, with a 500 kg equipment-load target.
Not fabrication-released. No load, cooling, mounting or compliance rating has been established.
Welded hollow steel posts and crossbars sit behind the 1.5 mm aluminum skins. Depth ties follow the same maximum-550 mm station rule on every size. Rails are now 2 mm steel, with real square holes and independently adjustable front/rear positions.
Equipment → rail kit → upright → bolted bridge → welded chassis → gusseted foot bridge → threaded support → floor
The rounded satin crown, polished perimeter, side symbols and disc feet remain. The lower roll is now fixed. Side skins lift 12 mm before withdrawing; their relieved hems sit above the foot mechanisms. Concealed-latch envelopes are separate from the decorative release caps.
A complete supplier hardware fit, service latch sequence and bonding disconnect still need to be resolved before a handling prototype.
| Size | Body at reference depth (W×D×H) | Tie stations / side | Bare side skin estimate |

Same sections, sheet gauge, interfaces and appearance; cut lengths and support quantities vary. The 48U still needs its own deflection, handling and stability verification. Wall and glass variants need separate requirements. M1 mobility now has a separate 500 kg equipment rolling target; none of these configurations is load-qualified.
26 named closed solids, 288 true square rail holes, millimeter units. Solid validity and STEP round-trip checks passed. This is a scoped BREP assembly—not a mesh exported and renamed as CAD.
STEP excludes feet and their bridges, trim, doors, purchased hardware, rail brackets, bonding and ventilation. Tube corner radii and fold roots are idealized. Do not fabricate or load this partial assembly.
One 24U / 1000 mm freestanding mesh prototype, USD, researched September 15, 2026. Linked catalog prices are budget anchors, not quotes. Custom parts, finishes and labor are explicitly estimated; no order has been placed.

Add 25% prototype contingency, shown above. Engineering/CAD completion, FEA, tooling, fixture capital, load/thermal/transport testing, certifications, equipment, PDU, tax, freight and future production tooling are excluded. This is not a production unit cost. Request supplier quotations after the drawing/hardware gate.
Explore's Casters option now shows four 100 mm twin-wheel assemblies, reinforced mounting plates and steel subframe rails, with separate polished leveling feet. Rolling raises the feet 30 mm clear of the floor; Parked lowers them until the wheels are 10 mm clear. Overall height is body height + 145 mm rolling or + 155 mm parked.
The target is 500 kg of equipment plus actual cabinet mass during controlled indoor rolling and stationary support. The wheels use an industrial reference envelope; brakes, forks, fasteners, levelers and connections are approximate development geometry. Supplier fit, corner reactions, floor-sheet interfaces, swivel/brake access, stability and physical testing remain open.
The P1 STEP and bill of materials above exclude this mobility assembly. No rolling or stationary rating is established.
