A custom wall-mounted wooden shelf designed to house a Nintendo Switch 2 Dock (rotated 90 degrees), 2 Pro Controllers, and manage all cabling (HDMI, USB-C power, Ethernet). Built with standard pine boards from a Japanese hardware store and designed to mount under a wall-mounted TV.

Component Width Height Depth Weight
Switch 2 Dock (rotated 90 degrees) 115mm (4.5”) 201mm (7.9”) 51.2mm (2.0”) 383g
Pro Controller 148mm (5.8”) 105mm (4.1”) 60mm (2.4”)

The dock is rotated 90 degrees so it stands tall (201mm) but narrow (115mm), saving horizontal space on the 400mm shelf.

    Thickness: 25mm (1.0")
    Mounted flush with the front edge of the frame.
    The extra depth hides the gap between the 110mm
    divider and 120mm side panels, and creates a
    channel behind the shelf for cable routing.

Step-by-Step Build Instructions

Phase 1: Preparation

Step 1: Purchase Materials

Visit a Japanese hardware store (Kohnan, DCM, or your local home centre). Ask the staff to cut wood to size:

  • 「このサイズに切ってください」 (Kono saizu ni kitte kudasai) – “Please cut this to these sizes.”
  • 「これをサイズに合わせて切ってもらえますか?」 (Kore o saizu ni awasete kitte moraemasu ka?) – “Can you cut this to size?”

Step 2: Sand All Wood Pieces

After cutting, sand every piece before assembly.

120 Grit – First Pass (removes saw marks)

  1. Sand all cut edges and surfaces.
  2. Always sand with the wood grain, never across it.
  3. Use moderate, even pressure with long, smooth strokes.
  4. After the first pass, lightly mist the surface with water. This raises the wood grain.
  5. Allow 10-15 minutes to dry.

120 Grit – Second Pass (after grain raising)

  1. Sand again with 120 grit to remove the raised grain fibres.
  2. The surface should now feel noticeably smoother.

240 Grit – Final Pass (polishing)

  1. Sand lightly with 240 grit using gentle pressure.
  2. This creates a silky-smooth, splinter-free surface.
  3. Run your fingers over the surface to check for any rough spots.

Clean Up

  1. Wipe all surfaces with a damp cloth to remove dust.
  2. Allow to dry before assembly.

Step 3: Apply Wood Finish (Optional)

Apply oil or varnish (ニス – Nisu) to all surfaces before assembly. Follow the product instructions for drying time.


Phase 2: Cutting Holes

Step 4: Cut the Cable Entry Hole (Right Side Panel)

This hole allows HDMI, USB-C power, and Ethernet cables to enter the shelf from behind.

  1. Mark: On the right side panel, measure 20mm up from the bottom edge and 20mm in from the front edge.
  2. Draw: Mark a 100mm x 50mm (3.9” x 2.0”) rectangle.
  3. Drill: Using a 10mm drill bit, drill a hole at each of the 4 corners of the rectangle (drill just inside the lines).
  4. Saw: Insert your hand saw blade into one of the drilled holes and carefully cut along the marked lines to the next corner. Repeat for all 4 sides.
  5. Sand: Smooth the edges with sandpaper to prevent cable damage.

Step 5: Drill USB Cable Holes (Middle Shelf)

These holes allow USB-C charging cables to rise from below the middle shelf to the controllers sitting on top.

  1. Mark 3 hole positions on the middle shelf:
    • Hole 1: 100mm (3.9”) from left edge
    • Hole 2: 200mm (7.9”) from left edge (centre)
    • Hole 3: 300mm (11.8”) from left edge
  2. Centre each hole at 60mm (2.4”) from the front edge.
  3. Drill: Use a 10mm drill bit. Drill straight through the 20mm wood.
  4. Sand: Smooth hole edges to prevent cable damage.

Step 6: Drill USB Cable Holes (Internal Divider)

These holes allow cables to pass through the divider between sections.

  1. Mark 3 hole positions on the divider:
    • Hole 1: 105mm (4.1”) from the bottom edge
    • Hole 2: 210mm (8.3”) from the bottom edge
    • Hole 3: 315mm (12.4”) from the bottom edge
  2. Centre each hole at 60mm (2.4”) from the front edge.
  3. Drill: Use a 10mm drill bit. Drill straight through.
  4. Sand: Smooth hole edges.

Step 7: Cut the Dock Slot (Bottom Base) – Optional

If you want the dock to slide into a recessed slot rather than simply sitting on the base:

  1. Mark: On the bottom base, centred in the right-hand section, draw a 125mm x 215mm (4.9” x 8.5”) rectangle.
  2. Drill: 10mm holes at all 4 corners.
  3. Saw: Cut between the holes with your hand saw.
  4. Sand: Smooth until the dock slides in and out easily.

Phase 3: Assembly

Step 8: Drill Pilot Holes

For every screw joint, always pre-drill pilot holes to prevent the wood from splitting.

Screw Type Pilot Hole Diameter Pilot Hole Depth
35-40mm assembly screws 3mm (1/8”) 25-35mm (1.0”-1.4”)
20mm back panel screws 2mm (5/64”) 15mm (0.6”)
5.1mm x 56mm wall screws 4.5mm (11/64”) 45-50mm (1.8”-2.0”)

Technique: Wrap a piece of tape around the drill bit at the desired depth to act as a depth marker. Drill at medium speed, keeping the drill perpendicular to the wood surface.

Step 9: Assemble the Box Frame

  1. Attach side panels to the bottom base: Place the bottom base flat. Position the two side panels vertically on either end, flush at the front. Pre-drill 3-4 pilot holes per joint. Drive 35-40mm wood screws.
  2. Install the internal divider: Position it at the 200mm (7.9”) mark from the left edge – the exact centre. Pre-drill and screw through the bottom base into the divider (2-3 screws).
  3. Add the middle shelf: Position it at the desired height (roughly 200mm from the bottom base). Pre-drill and screw through the side panels and the divider into the middle shelf.
  4. Attach the top shelf: Place on top of the side panels. Pre-drill and screw through the top shelf into the side panels and the divider.

Step 10: Install the Back Panel

  1. Position: Place the 25mm thick back panel against the rear of the frame, flush with the front edge.
  2. Secure: Use 20mm screws every 100-150mm (4-6”) along the edges. Pre-drill with 2mm pilot holes.
  3. Check: Ensure cables can route behind the panel through the space created by the 25mm thickness.

Phase 4: Wall Mounting

Step 11: Locate Wall Studs

Use a stud finder (壁内探知機 – Kabe-nai Tanchiki) to find wooden beams behind the wall. If you have concrete walls, you will need masonry drill bits and expansion bolts.

Step 12: Mark and Level

  1. Hold the shelf against the wall under your TV.
  2. Use a level (水準器 – Suijunki) to ensure it is perfectly horizontal.
  3. Mark the screw hole positions with a pencil.

Step 13: Drill and Mount

  1. For wood studs: Drill 4.5mm pilot holes, 45-50mm deep.
  2. For concrete: Use a masonry bit (コンクリート用ドリル) to drill 60-65mm deep, then insert expansion bolts.
  3. Insert right-angle anchors into the wall.
  4. Screw the shelf to the wall using your 5.1mm x 56mm wall screws. Use a minimum of 2 mounting points (top and bottom). 4 points is recommended for maximum stability.
  5. Check level one final time after tightening.

Phase 5: Cable Management

Step 14: Route All Cables

  1. HDMI cable: From the TV, down behind the wall, through the cable entry hole in the right side panel, to the dock’s HDMI port.
  2. USB-C power cable: From the wall charger, through the cable entry hole, to the dock’s AC adapter port.
  3. Ethernet cable: Through the cable entry hole to the dock’s LAN port.
  4. Controller USB-C cables: From the USB-C hub (placed on the bottom shelf), up through the 10mm holes in the middle shelf, to the controllers sitting on top.

Step 15: Secure Cables

Use adhesive cable clips (ケーブルクリップ) on the back of the shelf and along the back panel to keep cables tidy and prevent them from dangling.


Power Requirements

Device Power Draw Notes
Switch 2 Dock 60W (20V/3A) Requires USB-C PD (Power Delivery)
2x Pro Controllers ~10W total (5V/1A each) Charges via USB-C
Total ~70W 65W+ charger recommended; 100W for headroom

Look for a charger with the PSE certification mark (PSE認証) when buying in Japan.


Safety Notes

  • Wall anchors must support a minimum of 10kg (shelf + all devices weigh approximately 2kg; the 10kg rating provides a 5x safety margin).
  • Ventilation: Ensure at least 10mm of gap around the dock on all sides for heat dissipation. Do not enclose the dock in a tight space without airflow.
  • Cable strain: Leave slack at all connection points to prevent damage to USB-C ports.
  • TV clearance: Ensure the shelf does not block the TV screen, IR sensor, or any ventilation openings on the TV.
  • Electrical safety: Use a PSE-certified USB-C PD charger (「PSE認証」– PSE Ninshou).

Problem Solution
Dock does not slide into slot Sand the slot edges until there is 5mm clearance on each side
Cables too tight in holes Enlarge holes to 12mm or drill an additional hole nearby
Shelf is not level Adjust wall anchor positions or add thin shims behind the shelf
Controllers will not charge Check USB-C cable orientation; the port is on the top edge of the controller
Wood splitting when screwing Use smaller pilot holes (2.5mm) and keep screws at least 15mm from wood edges
Back panel does not sit flush Check that side panels and dividers are square; sand any high spots
