Qirab™ Conservation Cradle - QCC50

An open-source manuscript repair support hardware design


The Qirab™ Conservation Cradle is an open-source book support design intended to securely hold books open during conservation treatment, scientific analysis, documentation, and preservation works. It facilitates a hands-free holding of the book in a stable and adjustable position without extreme pressure.

The plans for the QCC50 are freely available for anyone to contruct their own cradle. It is built from commodity materials and 3D printed parts.

The concept of the Qirab™ Conservation Cradle was inspired by the work of Roger S. Williams1 and the team at Northwestern University on the Adaptable Conservation Book Support2 and the subsequent 3D printed upgrades done at the Auckland War Memorial Museum3.

Jeff Peachy designed a similar “book fixture”4 for conservation work which he sells as a comercial product.


The design of the Qirab™ Conservation Cradle uses a 20mm aluminum profile frame mounted with 3D printed hinges onto a wood base. The base provides a clean and stable working surface where various 3D printed tools can be attached.

The 3D printed tools include a tool holder, a cold-shoe light mount, spatulas, rods, gray card holder and a magnetic tyvek/mylar strap holder. All are designed to be conservation safe for use on manuscripts or rare books.
