I am an electrical engineer and I am intensely involved in 3D printing. For me, it's not about decoration, but about functional, resilient parts. I mainly print with ABS, ASA, and PETG and focus on stable, reproducible processes. I work with Bambu Lab printers and optimize start G-codes, workflows, and material settings so that prints run cleanly even in series production. If a part is good, it must also work dozens of times in a row without problems. Here I share models that I use myself or that make practical, robust, and well-thought-out technical sense
