A5 Bookbinding Workflow Set — Black PETG, 9 Pieces

Prepare folded paper for sewing and lay out a handmade book cover with one set of 3D-printed tools. The pieces are separate, so you can use the cradle and cover-layout tools at different stages of a project.

• One A5 punching cradle: approximately 224 × 55 × 30 mm, with a 221 mm usable length from its end stop and a roughly 60-degree opening. The 215 × 2.4 mm nominal slot passes through the base and starts 3 mm from the inside of the end stop.
• Six board-gap spacers: two each in nominal 5, 6 and 9 mm widths.
• Two corner-marking templates: nominal 2 and 3 mm allowances, for marking with a pencil.

All nine pieces are black PETG. The cradle is intended for a folded edge up to 210 mm long, such as A5; paper extends beyond its sloping faces. The corner templates are marking aids, not blade guides or calibrated gauges. Choose the gap and corner allowance to suit your own materials and binding method.

Not included: awl, cutting tools, pencil, paper, boards, glue or protective mat. Place a suitable protective mat beneath the cradle before piercing: its slot does not protect the work surface or stop the awl. Use your own paper template for hole positions.
