MONOLITH OFFSET — Coralboard SL Enclosure / R1 Prototype

MONOLITH OFFSET — Coralboard SL enclosure / R1 prototype

Twenty staggered capsule vents and a coral side service panel give OFFSET a compact, technical appearance. The chalk shell and recessed midnight plinth keep the overall form quiet. R1 replaces loose panel registration with two screws, allowing the panel to be removed for service.

STATUS

R1 is a printable prototype checked digitally against the official Synaptics Coralboard SL reference. Physical printing, assembly fit, cable clearance, fastener torque and thermal performance have not been tested. The images are Blender Cycles renders of the R1 geometry, not photographs of a printed build.

DESIGN

20 capsules in four rows; each 8.7 × 2.5 mm. Nominal main body: 88 × 73 × 24.65 mm, including nominal feet; screw heads and small accent projections can extend beyond that envelope. Front USB-A/USB-C openings, recessed button access, side microSD service access and a rear ribbon exit are included. Top headers are accessed with the lid removed. Actual plug overmolds and accessories need a physical check.

FILES

Four printed parts: tray, lid, plinth and accent panel. Individual STL and 3MF files are in millimetres, placed on the bed in their intended print orientation. A generic multi-object print-layout.3mf is also included. Select your own printer/material settings and check bed fit; the 3MF files do not contain a printer profile or ready-to-run G-code. Print only the enclosure parts. The reference board and hardware shown in the renders are not printed components.

PRINTING AND COLORS

Suggested first prototype: PETG, 0.4 mm nozzle, 0.2 mm layers, four perimeters, five top/bottom layers and 20% infill. Inspect tray opening bridges and local flanges in the slicer; use removable supports where needed and keep them out of screw pilots. See PRINT-SETTINGS.txt for orientation and support guidance. Chalk tray/lid: #F3F4F2. Midnight plinth: #151C34. Coral accent: #F65B66. These are approximate design colors, not official brand or filament matches.

ASSEMBLY

Use four M2.5 × 5 mm board screws, four M2 × 8 mm lid screws, four Ø8 × 1 mm adhesive feet and a material-compatible adhesive for the lower stack. Screw lengths are measured beneath the head. Board pilots are Ø2.1 mm; lid pilots are Ø1.7 mm. Prepare threads carefully and verify usable depth on the actual print. No insert pockets are provided. Nominal board-screw bottom clearance is only 0.30 mm; lid-screw clearance is 1.65 mm. Also required: two M2 × 5 mm panel screws. The panel uses Ø1.7 mm pilots in the tray ledges; do not glue it. MicroSD service may require panel removal. Follow ASSEMBLY.txt for sequence, thread preparation and adhesive placement.

DIGITAL CHECKS

Each printed part passed closed-solid, positive-volume and consistent-winding checks. Boolean checks found no part-to-part or reference-board overlap above 0.001 mm³. Vertical board insertion and lid removal were screened at five discrete heights. Modeled screws cleared the board reference. The print layout imported and sliced successfully in OrcaSlicer 2.4.1 using a sample 0.4 mm PETG profile; slice again for your own printer and filament. These checks do not establish physical fit, continuous assembly clearance, strength or cooling performance. No protection or thermal rating is claimed.

BOARD REFERENCE

Fit is based on the official Synaptics Coralboard SL STEP reference: https://www.printables.com/model/1859306-synaptics-coralboard-sl/files That reference has a separate Apache-2.0 license and attribution. It is not an enclosure part and is not included in the printable file set.
