| Text | This Jaflapse model (sanbow) allows you to obtain a box with two side handles for easier
handling.
1. Take a square sheet of paper. 2. Form a valley fold by bringing the top edge over the bottom edge. We obtain a rectangle with two layers linked by an upper hinge edge. 3. Form a valley fold by bringing the bottom edge of the front layer upwards over the hinge edge. 4. Flip the fold from right to left. 5. Repeat step 2 and step 3 applying them to the front layer. We obtain a rectangle with 4 layers, two being free, two interior being fixed. There are two lower hinge edges, a front upper free edge, a rear upper free edge and, in between, a hinge edge. 6. Form a valley fold by bringing the lower front hinge edge to the upper edge. 7. Form a mountain fold by bringing the lower rear hinge edge to the upper edge. We obtain an elongated rectangle with 8 thicknesses, organized symmetrically around the innermost upper hinge fold. 8. Open the rectangular shape around the innermost top hinge crease. We obtain a rectangle with three flaps: a rear, fixed, linked by an upper fold-hinge and a lower fold-hinge with two free flaps of quadruple thickness. 9. Form the left edge with a mountain fold on the right edge. We obtain a rectangle oriented horizontally. Turn it until it is vertical, the bottom being formed by the fold-hinge that has just been made. We obtain an object made up of two flaps linked by the lower fold-hinge. Each flap is formed of a rectangular rear layer linked by a left hinge fold and a right hinge fold to a triple thickness accordion type structure which gives, in the end, a double thickness flap linked to the bottom rectangle and equipped with a right hinge edge, an internal left hinge edge linking a last free layer. The two flaps meet in the middle of the vertical rectangle, forming a median space. 10. Form the lower left corner into a valley on the middle space (45¡ fold). Unfold and reform the fold into a mountain fold. Unfold. 11. Repeat step 9 with the lower right corner. 12. Open the front flap by sliding your thumb, from the top, between the attached double-thickness flaps and the rest of the flap (there is a free flap on either side of the middle space and the bottom flap ). Progress downwards and tilt forward the top of the flap which is widening on either side of the center line. Flatten completely. We obtain a symmetrical shape around the center line, with 6 sides. We recognize a long double-thick lower edge, bordered by two vertical sides, which each continue with two small sides inclined at 45¡ towards the inside of the figure and, finally, a small horizontal edge which closes the hexagon. 13. Flip the fold from right to left. 14. Repeat [step 11] with the rear flap. We obtain two hexagonal flaps connected by a complete system of hinges. 15. Form a 45¡ valley fold by folding the lower left corner of the front hexagonal flap along the middle fold. 16. Form a 45¡ valley fold by folding the lower right corner of the front hexagonal flap along the middle fold. We obtain a figure symmetrical with respect to its median axis, comprising 5 sides, with a point downwards (which we have just formed), a point on either side of the median axis and an upper edge horizontal. 17. Form the left point with a vertical valley fold on the central axis of the hexagonal flap. Do the same for the right tip. We obtain a flap with a horizontal upper edge bordered by two vertical sides which meet at a point at 45¡. The structure of this flap is very complex. 18. Take the tip and bring it through a valley fold at 90¡ from its initial position, folding it as far as possible without opening the shape. 19. Flip the fold from right to left. 20. Repeat all the operations from step 14 to step 17 by applying them to the front hexagonal flap. We now have two points orthogonal to the general plane of the hinge structure. 21. Gently pull on the two tips to move them away from each other. The hinge structure unfolds and the box appears. All you have to do is put it in shape. |
