Dispenser for syringe of flux or solder paste

I got tired of manually squeezing the fluid out of the syringe with my thumb and decided to build something that allows me to squeeze it with my index finger. I didn't like the pistol-shaped design of other things, so these will take up more space on the table. This dispenser is compact and can be placed upright or in a special stand similar to a soldering iron holder. Everything was printed without support.

This dispenser was designed for a 19.5mm syringe, but it will also work with a 14.5mm syringe – you'll just need to print another plunger. This plunger will fit large syringes too, so only this part needs to be printed. I added an improvement:
