I have lost or broken several of the Fabrikor keys and am down to a single key for all the cabinets in my home. This is a printed replacement since all Fabrikor cabinets (including different sizes) use the same one. Please use caution and a soft hand with this since a plastic key can break inside the lock and be a pain to remove. I printed with the flat side facing down with 100% infill for strength and in PETG because that was what was loaded. PETG might not be ideal since it is more flexible than other filaments. The key works reasonably well, although some times it requires a little bit of repositioning to properly “catch”.
