Lead 3D printing technician at FS3D.CZ, based in Czechia. I design functional, print-ready parts, tools and machine upgrades. Models are parametric, documented and tuned for reliability: accurate tolerances, snap-fits, threads, press-fits; minimal supports and fast print times. Validated on Bambu Lab printers in PETG/ASA; includes clear print notes and orientation tips. I value real-world testing and iterate from feedback. Open to remixes, bug reports and collaboration.
