Sorry, this is a test item, not suitable for beginners. It works as expected. I'd like to express my gratitude to two individuals who inspired me to create this project. Their work can be found on YouTube, specifically in the video titled "TJNK66PdgK0." For reference, I've uploaded the step-by-step instructions for building this project. It took me five hours to design it, and although there are numerous design flaws, fortunately, it functions properly. I'll leave it up for a while before providing detailed instructions once I have some spare time. Regarding the materials needed, one 10ml syringe serves as both the cylinder and piston. You'll require two of these syringes to complete the project. In addition to the syringes, you'll need five small bearings with specific dimensions: 2x5x2.5 x3 and 6x15x5 x2. Also required are an M2 screw that's 25 mm long, an M3 screw that's 40 mm long, and has 14 threads, as well as two more M3 screws with lengths of either 10 or 16 mm. Lastly, you'll need a seal ring measuring 8x1.5 x3. Installing this project requires considerable technical expertise. When printing, be sure to place the 6x15x5 component in its designated position.
