Open Research Hardware: A Modular 3D printed Toolkit for Positioning and Micromanipulation
Year: 2026
Type: article
Abstract: Scientific experiments frequently require precise translation, rotation and manipulation of small objects, yet the mechanical tools used for these tasks can be expensive and specialized. This work presents a collection of open-source, 3D-printed mechanical tools developed as low-cost building blocks for microscopy and small-scale experimentation. The toolkit comprises one-, two- and orthogonal-axis translation stages, in-plane and out-of-plane rotation stages, a three-axis micromanipulator, and switchable magnetic and suction mounting bases. The designs combine FDM-printed structures with inexpensive standardized components such as rods, springs, screws and ball bearings, to provide sub-100-micron positioning. Rather than a single instrument, the collection enables researchers to assemble customized positioning systems from modular components. The work explores how desktop additive manufacturing and open hardware can provide accessible precision mechanisms for research environments while allowing designs to be reproduced, modified and further developed by their users.
