V-fold crease and flange study

A good fit for your idea?

Start with the four-page base-and-insert study. Choose the five-page companion study if you want the separate optional flange. Letter and A4 preserve the component dimensions; choose the paper you will print. Earlier editions remain available in the complete file list.

Materials for the study

Use paper, a ruler and pencil for measurement; a blunt scoring tool is optional for a separate crease study. Scissors are optional for the outer contour.

The revised study needs no glue or mounting template. Keep the insert separate from the base.

Choose the revised study pages

The four-page base-and-insert study has a reduced overview on page 1, the base reference on page 2, the insert study on page 3 and instructions on page 4.

The five-page companion study has a reduced overview on page 1, the base reference on page 2, the insert study on page 3, the separate optional flange on page 4 and instructions on page 5.

Print the matching paper edition at 100% and measure the 50 mm reference bar; page 1 is a reduced overview, not a cutting sheet.

Original measured parts

Base: 180 x 128 mm, with the hinge 90 mm from the left edge, dividing two 90 x 128 mm faces.

Insert: 106 mm overall width and 93 mm overall depth; the three-score junction is 56 mm below the top and the center score is 37 mm long.

The diagonal arm offsets are asymmetric: 45 x 56 mm and 29 x 56 mm.

The optional companion is 62 x 44 mm overall, with an 8 mm flange and a 62 x 36 mm face; no insert attachment point is assigned.

Read the existing marks

The dark outer contour is the cut reference and the dark dashed paths are the original scores. Pale outlines bound shaded regions and add no cuts or scores.

Identify the three insert scores without assigning mountain or valley directions or gluing the wings. New creases, slits or mounting tabs would require a separate redesigned resource.

The revised sheets are flat crease and flange studies. They do not promise a rise angle, flat closure, working attachment, strength or finished pop-up mechanism.
