Here is a tiny 3D‑printed etching press I made, based on the Open Press Project’s free design. I printed it in Overture Rock PLA and used many of their suggested settings, but tweaked infill, orientation, and other parameters per part to better match how each component is stressed in use. For the pressure adjustment, I used two 5 mm thumb screws with matching nuts from Amazon: [https://a.co/d/01MTDpoe](https://a.co/d/01MTDpoe). For printing (with suggested print settings) and assembly, please follow the original instructions and STL download here: [https://openpressproject.com/blogs/news/](https://openpressproject.com/blogs/news/)
