Wandy3D laser layers - garden-gnome

49 layers of 3 mm sheet material, 52 pieces on 2 sheet(s)
of 297 x 210 mm (A4). Finished stack: about 65 x 52 x 150 mm.

COLOURS
  red   #ff0000  = cut (through)
  blue  #0000ff  = engrave / score (a light pass on the surface)
Set the red layer to cut through your material and the blue layer to a light score
or line engrave. Kerf compensation of 0.15 mm is already applied: outlines are
0.075 mm larger and holes 0.075 mm smaller, so parts come out true to size.
If your laser's kerf is different, make the layers again with that value.

BUILD
1. Cut every sheet. Each piece is engraved with its layer number (L1);
   several pieces of one layer carry letters (a, b, ...). Numbers sit under the
   next layer where there is room, so most are hidden once glued. Tiny pieces
   without room for a number are listed in layers.csv.
   1 bits smaller than 20 mm2 were left out (too small to cut).
2. Stack from layer 1 (the bottom) upwards, engraved side up. All numbers are
   engraved the same way round: keep them reading the same way as you stack.
3. Align each layer on the dowels, and use the engraved outline of the next layer.
4. Glue with wood glue (PVA) and press each layer for a moment; let the stack dry
   under light weight. Cardboard works for a quick test build.

DOWELS (3 mm round rod, e.g. wooden dowel or bamboo skewer; holes are 3.1 mm)
  1 x 132 mm - through layers 1 to 44
  1 x 12 mm - through layers 44 to 47
  Push each dowel in as you stack; it ends flush with the top of its last layer.
