A Boat for a Message
Build an open PLA boat from four filled parts. Once cool, place a small paper message inside and display it on a dry shelf.
Your outcome: Build a three-dimensional boat that can hold your own small paper message.
Illustration of the finished construction. Full-size (1:1) templates are supplied on a separate sheet.

Draw and fill the bottom
Choose PLA colors for the bottom and walls. After arranging the templates, trace the triangular bottom. Fill from the bow with short strands running from edge to edge, side by side with a slight overlap. Join every strand to the outline. Leave the bottom flat to cool.
Check: The pointed bow is visible, and the entire fill is connected to the outline.
If it does not work: Bridge the gap with a short PLA strand. Remake a warped bottom flat before assembly.

Make the first side
On the upper template, trace the rectangular side. Starting at a short end, fill it with strands connecting the long edges; each new strand touches the previous one. The images show the outline, the half-filled part and the complete part. Leave the part flat to cool.
Check: The side has a closed outline and connected fill; the corners lie flat.
If it does not work: Fill the gaps between the strands. Do not bend the PLA; remake a warped part before joining.

Make the second side
When the first side and bottom have cooled, slide just the BURTY paper template out of the upper area and into the clear lower 14 × 7 cm area. The cold parts stay in place; the other templates do not move. Trace and fill the second side in the same way. You may choose a different color. Cool it flat.
Check: You have two separate sides with the same dimensions; the paper does not overlap the other templates.
If it does not work: If the template has shifted, stop drawing. Position the paper in the clear area, align it with the cold outline, and only then continue.

Add the stern
On the template on the right, trace and fill the smaller stern rectangle. Join adjacent strands to the outline. Allow it to cool. You now have the bottom, two sides and the stern; you may take a break at this point.
Check: The four parts are rigid, flat and completely cool.
If it does not work: Add any missing fill connections. Do not lift a warm part or fit it to the hull.

Set up the three walls
Separate the cooled parts from the work surface; leave the bottom flat. Position the first side, second side and stern, in that order, on the edges of the bottom. The short ends of the sides meet to form the bow.
The helper first holds the sides, then grips both upper rear corners, holding one side together with one end of the stern in each hand. Put the pen down before tacking.
Check: The walls stand vertically, their lower edges rest on the bottom, and the three corners touch without being forced together.
If it does not work: Reposition the parts. Do not bend cold PLA. If an edge is warped, remake that flat part.

Tack the three corners
The helper continues to hold the cold upper sections of both rear corners. Tack the bow, rear corner 1 and rear corner 2, in that order. From the outside, run approximately 9 mm of PLA upward across both touching edges. After each tack joint, move the nozzle away and hold the parts in position until cool.
Keep fingers on the cold upper section.
Check: Each of the three corners has a short joint that grips both walls; the hull retains its shape.
If it does not work: If a joint caught only one wall, correct the position and add a short tack joint across both. Allow it to cool while continuing to hold the upper section.

Join the walls to the bottom
While the cold upper section is supported, add two separate strands from the outside at each of these points: side 1, side 2 and the stern. The strands at the sides are approximately 2 cm each; those at the stern are approximately 1.2 cm each. Every strand grips the wall and the edge of the bottom. Cool each strand after applying it.
The bottom remains flat throughout; do not apply PLA underneath.
Check: Six short strands join the three walls to the bottom; the gaps between the strands remain visible.
If it does not work: If a weld missed one edge, let it cool, correct the position and add a short joint across both edges. Do not lift the warm hull.

Position your own boat
After the welds cool, release the walls and check that the boat stands by itself. Write a small paper message, fold it and place it inside the open hull. Set the boat on a dry shelf.
Check: The boat stands by itself, none of the walls pull away from the bottom, and one light paper message rests inside the open hull.
If it does not work: Hold a loose joint by the cold upper section, join it with a short PLA strand and allow it to cool. Do not force the rigid hull straight.
