ContourDock M4 - Stable One-Piece Wave Stand for MacBook Air

ContourDock M4 - One-Piece Wave-Rail MacBook Stand

ContourDock M4 is a sculpted vertical laptop stand built around two continuous wave-shaped support rails. The low center keeps the silhouette light and modern, while the higher tapered ends provide broad lateral support. A wide 100 mm base and optional anti-slip feet improve stability without turning the stand into a bulky block.

FEATURES

• Original one-piece wave-rail design
• Prints upright as supplied
• No support material required
• Wide, low-profile base for improved stability
• Tapered slot for easy insertion
• Recessed channel for a protective floor pad
• Four underside recesses for 12 mm silicone or rubber feet
• High-resolution, watertight manifold STL

COMPATIBILITY

Designed around bare MacBook Air M4 models:

• MacBook Air 13-inch — 11.3 mm thick
• MacBook Air 15-inch — 11.5 mm thick

The raw slot measures 14.9 mm at the bottom and gradually opens to 17.8 mm. With 0.75 mm self-adhesive felt on each inner rail, the effective lower gap is approximately 13.4 mm. This leaves a controlled clearance for the bare aluminum laptop while protecting it from scratches.

The stand is not intended for laptops fitted with hard shells, thick skins or protective cases. Measure your device before printing if it is not one of the listed MacBook Air models.

DIMENSIONS

• Approximately 190 × 100 × 51 mm
• One printed component
• 12 mm underside foot recesses
• Recommended felt thickness: 0.75 mm per side

PRINT INSTRUCTIONS

• Orientation: upright, flat base on the build plate
• Nozzle: 0.4 mm
• Layer height: 0.20 mm; use 0.16 mm for a finer surface
• Walls/perimeters: 4–5
• Top layers: 5–6
• Bottom layers: 5–6
• Infill: 30–40% gyroid or cubic
• Supports: none
• Brim: optional 5 mm if bed adhesion is unreliable
• Outer-wall speed: 35–45 mm/s for the cleanest curves
• First-layer speed: 15–25 mm/s
• Seam: place toward the rear or inside the slot
• Wall generator: Arachne/variable-width is recommended when available

The only downward-facing details are four short 12 mm bridges above the underside foot recesses. A normally calibrated printer should bridge these without support.

DEVIL DESIGN PET-G STARTING PROFILE

• Nozzle: 230–240 °C; start at 235 °C and follow the range printed on your spool
• Bed: 70–80 °C; start at 75 °C
• Part cooling: 30–50% after the first layers
• Retraction: use the calibrated PET-G value for your printer
• Dry the filament if stringing, bubbles or rough surfaces appear

PLA also works and produces crisp edges. PET-G is recommended when you want improved toughness and a less brittle stand.

FINISHING AND USE

Apply approximately 0.75 mm self-adhesive felt to both inner rails and the recessed floor channel before inserting the laptop. Add four 12 mm silicone or rubber feet underneath for maximum grip.

Always place the laptop centrally and avoid strong cable pull or side impacts. The geometry has been digitally validated as one closed manifold component, but the model has not yet been physically print-tested. A first physical fit and stability test is recommended before everyday use.
