This document discusses how to create affordable motorized rotation mounts for optical systems using a 3D printer and off-the-shelf components. The mounts are designed for 1″ optics and can be used for reflective or transmissive elements. The performance of these DIY mounts is compared to commercial systems, showing similar results at a fraction of the cost. Surprisingly, the mounts perform well in controlling lasers for optical tweezers and Raman spectroscopy, achieving a resolution of $0.03$ percentage points. This innovative approach provides an inexpensive solution for automation and scanning in optical setups.
