Syringe | Funtional

This is a fully functional syringe — printed as a fun proof of concept.
It works the same way as an injection-molded syringe, just a bit louder and less smooth because of the layer lines. 😄💥

The plunger expands the barrel slightly to create the seal, which is why you should:

🔧 Print Tips
• Print both parts in the same orientation
• Lubricate the plunger before first use (water/oil/grease)
• Move it up/down a few times so it can break in
• When drawing water, pull slowly to avoid air slipping past

⚠️ Disclaimer
To achieve a proper seal, the barrel wall is designed thin enough to flex, this means the barrel is fragile, so handle it with care.

🎨 Materials
• PLA works great
• Transparent PETG for the barrel makes it look realistic and lets you see the liquid inside 👀💧

A fun and surprisingly capable little engineering experiment 🚀

Just keep in mind: it won't perform as well as a real injection-molded syringe.
