Cube Gift Box
A 50 mm cubic gift-box body with a removable square cap. Two cross-shaped nets use integral tapered corner glue tabs; the 52 mm lid has a 15 mm skirt and 1 mm clearance per side.
Materials
- 180-220 gsm cardstock (two sheets)
- Scissors
- Ruler and blunt scoring tool
- PVA paper glue
- Small clips or removable tape
Finished size: 52 x 52 x 50 mm closed; body 50 x 50 x 50 mm; lid 52 x 52 x 15 mm
Steps
CutValley foldMountain foldGlue area
-
Check scale and cut body
Print at 100% actual size. Check the ruler measures 50 mm. B1 center must measure 50 x 50 mm and each wall 50 mm deep. Cut its solid perimeter, preserving all four tapered 8 mm tabs.
-
Score and dry-fold body
Score four 50 mm center edges and four 50 mm tab hinges. With printing facing up, raise walls 90 degrees toward you. On the two tab-bearing walls, fold tabs 90 degrees inward. The two plain walls wrap outside these tabs; dry-fit a square opening.
-
Glue body corners
Lower plain walls for access. Apply a thin film to the reverse of the four dotted patches. Raise one plain wall against its two inside tabs, overlapping up to 8 mm; align bottom corners and top rims. Repeat on the other plain wall. Clip until set; keep the opening 50 x 50 mm and both opening diagonals about 70.7 mm. Let dry fully.
-
Cut and fold lid
Check L1 center is 52 x 52 mm with four 15 mm skirts. Cut the perimeter, score all eight dashed hinges, and fold a shallow tray with printing inside: skirts and tabs each turn inward 90 degrees.
-
Glue lid separately
Glue the reverse of the four dotted tab patches. Place tabs inside the two plain skirts with up to 8 mm overlap. Match skirt corners and hold square: opening diagonals about 73.5 mm. Clip and dry completely away from B1 so the cap cannot bond to the body.
-
Close and reopen
Turn L1 upside down, printed side inward, and lower over B1. The 52 mm cap centers over the 50 mm body with 1 mm nominal clearance on each side. Its skirts cover the upper 15 mm of B1; seat the cap on the body rim without glue. Lift the whole lid to open. Test with dry light contents; if it binds, check squareness and glue lumps rather than forcing it. Record fit in the physical trial.
Notes
The 3D model shows each piece in its finished, idealized shape; the exploded view only spreads the pieces apart. It is not a paper-physics simulation: curved shapes are forming guides, not exact physical folding or proof of developability, and intermediate fold shapes are not supplied.
- Original construction. Physical printing and assembly verification pending.
- B1 is a 150 x 150 mm net; L1 is an 82 x 82 mm net. Cut each once. Each has one square center, four walls and four integral 8 mm glue tabs.
- All dashed folds are 90-degree valleys with the printed face inside the tray. Glue the REVERSE of each dotted tab patch, not the visible printed face.
- Flat and formed triangles correspond exactly without stretching. Paper and glue thickness are omitted; lap layers coincide. Real finished dimensions vary with stock.
- The cap is not glued to the body. Its nominal 1 mm side clearance allows for paper layers, but fit and repeated opening require physical testing. Use for light dry gifts.
- The 3D shows the closed box. Steps place complete formed parts, not continuous folds.
