RetroTerm-12 — Framework Laptop 12 Mainboard Retro Terminal Enclosure (7-inch Display)

A 1990s-terminal-inspired wedge enclosure for the Framework Laptop 12 mainboard. The board lives in the lower tub; a 7-inch display mounts on the 45-degree sloped face behind a beige faceframe. All four USB-C ports remain accessible, cooling is preserved, and the board is secured on five M3 heat-set-insert mounts aligned to Framework's official STEP CAD.

FEATURES

- Wedge terminal aesthetic: 45-degree display slope, charcoal tub, beige faceframe

- Display opening exactly 165.5 x 105.5 mm; nominal 7-inch panel envelope 165 x 105 mm. Panels vary widely — measure your specific panel before printing. Ears are slotted/adjustable.

- Mainboard: Framework Laptop 12 (218.8 x 107.4 mm) drops into the open tub; standoffs seat in 8.8 mm pockets

- Mounts: 5x captive M3 heat-set inserts at the official STEP standoff positions

- Ports: all four USB-C accessible via side cutouts (2 per side)

- Cooling: tub-bottom fan-intake slots, deck slots, slope side/rear vents, side exhaust slots. Do not block.

- Power: directly accessible — lift the service-hatch panel (finger scoop, no tools) and press the board's onboard SW1 tact switch. No drilling, no guessed hole location.

- Keyboard tray: deck with front lip for a compact keyboard

- Printability: support-free except the slope shell's 45-degree interior face (at the 45-degree maximum; interior, not visible). All parts fit 256 mm beds.
