Materials and accessories

QtyPart
1LED tea light
1Wood glue (water-resistant D3)

Also: sandpaper (grit 120 and 240), a utility knife or fine saw and, for joints, a rubber mallet.

Carving and finishing

  1. Clamp the workpiece flat on the spoilboard or secure it with double-sided tape, and set the origin as shown in the carving assistant.
  2. First cut the windows with the 2 mm end mill, then the jointed parts with the 3.175 mm end mill. Do not file away the corner reliefs at the fingers, they are intentional.
  3. Free the parts at the holding tabs with a utility knife or fine saw and sand the tab remains flush.
  4. Before gluing, dry-fit everything. If a joint is too tight, increase the clearance by 0.05 mm and carve the part again; if it wobbles, reduce it.

Assembly and final touches

  1. Fit the four walls around the base: the two walls with full fingers at the bottom edge face each other. Put a little glue into the joints and hold with tape until dry.
  2. Glue tracing paper behind the windows if you like. Only use an LED tea light, never an open flame.
