Bookspine Rounding Form

This bookspine rounding form is a simple workshop tool for bookbinding and book restoration. It is designed to support the controlled rounding of book spines after sewing, helping achieve an even, consistent curvature without damaging the text block.

The tool features multiple concave channels, allowing it to accommodate different book thicknesses. It can be used together with the back of a screwdriver or any rounded tool that fits the mold , and works well with PLA, PETG, or wood-filled filaments, 20% infill prefered, because of longevity.

Suitable for hobby bookbinders, conservators, and anyone working on handmade or repaired books.
