The implementation of educational artefacts based on new technologies depends on the skills and motivation of lecturers in the field. Aside from early adopters, lecturers often rely on best practices and exemplifications for their specific subject of teaching. In this work, we present how we applied end-user programming tools for Mixed Reality and the area of technical drawing, construction, and Computer Aided Design. With this approach, we created MACARONI, a Mixed Reality technical drawing section view tool. In an expert user study, we collected insights on how lecturers at our institution perceive Mixed Reality as teaching tool, exemplified by MACARONI. Also based on the evaluation of our solution by the participating lecturers, we reflect on autobiographical design for the purpose of tapping in technologies for others. We argue that it helps to showcase the technology and how it can be applied for those lecturers, who did not consider using the technology before.
