Print-in-place Instax photo book for mini, square, wide

A little photo book for your Instax prints, so they stop living in a shoebox. Each page holds two photos, and the whole thing prints already assembled, hinges and all. Add pages for a thicker book, or loosen the photo slot if your prints fit snug.

Notes
Print the whole book as one object (print group 'book'), standing closed as exported: about 64 g and 2 h 31 min at 2 walls / 15% infill for the default 3-page mini book (3 walls / 15%: about 68 g, 2 h 48 min). The file is already turned 90 degrees so the page faces run parallel to the bed's Y motion

Assembly

  1. Print the book as one piece, standing up exactly as exported. No supports and no brim.
  2. Let it cool on the plate, then lift it off as one block.
  3. Free each hinge gently: rock each page a few degrees back and forth, then open it further, until every joint swings freely.
  4. Slide each photo in from the open top edge, picture facing out through the window, until it rests on the bottom lip. Every page takes two photos back to back.
  5. Stand it as a zigzag (about 120 degrees between pages) to display it, or fold it flat to store it.

Good to know

  • Checked in the Loftsmith engine, not test printed. The 0.35 mm hinge gap is a starting value: if a joint is fused after printing, reprint with a larger Hinge radial gap.
  • Film thickness (1.0 mm) and the top border position (7 mm) are estimates. If photos are tight or loose, change Photo slot clearance; a 2-page book makes a quick test print.
  • The pages are tall and thin while printing (92 mm on a 5.5 mm foot). Keep the page faces along the bed's motion and slow the upper layers as described in the print notes.
  • Photos are held on the sides and bottom and slide in from the open top. Only friction stops them sliding out, so shaking the closed book upside down can drop them.
  • Fits Instax mini, square and wide film only. Borderless 4x6 in prints are not supported, because the lips would cover part of the picture.
  • PLA softens around 55 °C; do not leave the book in a hot car or sunny window.
