I think you’re overestimating the complexity of an stm setup. There exist small coffee machine sized stm machines because the principal behind the operation is relatively straightforward. People have made diy stm machines using piezo electric buzzers as the component that moves a tungsten needle over a sample. It’s relatively easy to make atomically thick tungsten needle points because of how it fractures along its grain structure. The tech behind the principle of operation of an stm is already ubiquitous.
