Alcohol Dispenser

Alcohol Dispenser It may seem like an insignificant and barely noticeable tool on the table, but an alcohol dispenser is used constantly. However, its malfunction or absence causes a whole range of inconveniences. Over the years, I have tried many dispensers, but none satisfied me for various reasons. Some were unstable on the table and tipped over when pressed, while others were poorly sealed. A few years ago, I bought a small polyethylene dispenser with a flip-top lid. Its mechanism was perfect, but the material itself was short-lived—the lid broke. This led me to the idea of combining its pump with my own printed model, which would be stable and fully meet my requirements. I created the drawings and got to work. To assemble it, you need to extract the pump from the original dispenser—it is tightly secured but can be disassembled. You will also need the small tube left in the lid, which must be carefully cut off. The method depends on the available tools: you can do it manually, with a drill, or on a lathe, as I did. The diameter of the remaining flange of the tube is 13 mm. My model offers several usage options. It can be simply a container with a lid for storing liquids or a fully functional dispenser. The outer cap is not mandatory since the pump itself already has a sealing valve with a spring and a ball. Assembling the pump with the printed lid requires effort, but if you have the right skills, you will manage. If you have doubts, it’s better not to start at all. Printing I printed the lid from ABS. The material is not critical since its contact with alcohol is minimal. Ideally, the bottle should be printed from polyamide or polycarbonate, but these plastics require drying and experience. I used PETG instead—it is inert to alcohol and easy to print. However, not all PETG types have good interlayer adhesion. If the seal is imperfect, you can treat the inner walls with dichloromethane, which will fill microcracks. Alternatively, you can increase the plastic flo
