3D Wooden Puzzle Assembly: Gundam vs Miku Paper Craft

Quick answer

Assemble the Wa-gu-mi Gundam RX-78-2 3D wooden puzzle by sorting laser-cut bamboo sheets and dry-fitting before gluing. For the PIPEROID Miku paper craft, cut precisely, fold along scored lines, and insert pipes without glue.

Step-by-step assembly guide

1. Step 1: Organize all pieces before starting: Lay out the wooden or paper sheets and identify each piece using the included diagram. Separate pieces by sheet number or color code. For the Gundam kit, keep bamboo sheets flat to avoid warping. For the Miku kit, flatten curled paper sheets under a book. Check that all pieces are present before you begin; missing parts are easier to spot now than mid-assembly.
2. Step 2: Remove pieces carefully from the sheet: For the wooden Gundam puzzle, gently push pieces out from the back using your thumb. Do not twist—this can break thin tabs. For the Miku paper craft, use a craft knife or scissors to cut cleanly along perforations. Avoid tearing the paper by cutting in one smooth motion. A broken tab on a wood piece may require glue; a torn paper edge can be hidden but weakens the joint.
3. Step 3: Dry-fit before applying any adhesive: For the Gundam wooden kit, assemble sections without glue first. Confirm that all tabs align and slots are not too tight. If a piece is stuck, sand the tab lightly with fine-grit sandpaper. For the Miku paper craft, insert pipes into holes without pushing all the way—check alignment before final assembly. Dry-fitting reveals misalignment or warping early; adjusting now saves frustration later.
4. Step 4: Apply glue sparingly to wood joints: Use a small amount of wood glue on each tab of the Gundam kit. Apply with a toothpick to avoid excess. Hold the joint for 30 seconds until set. Wipe away squeeze-out immediately with a damp cloth. The Miku kit requires no glue—just push pipes fully into holes once alignment is confirmed. Too much glue can seep onto visible surfaces and ruin the finish; less is more.
5. Step 5: Allow full cure time before handling: Let the Gundam wooden model rest undisturbed for at least 2 hours after gluing. For larger sections, wait overnight before attaching them. The Miku paper craft is ready immediately after inserting all pipes—no drying time needed. Rushing to handle a glued model can cause joints to slip; patience ensures a sturdy build.
