I got tired of squeezing the flux out of the syringe with my thumb and so I decided to create this thing to squeeze the flux out with my index finger. All other things are in the shape of a pistol, which I did not like and these will take up a lot of space on the table.
This dispenser is compact and can be placed vertically or in a special stand similar to a soldering iron stand.
Everything is printed without support. I used PLA but I think any material that is strong in bending will do.
Use an M3x25 as an axle for attaching the large arm and a piece of filament (1.75mm) as an axle for attaching the small.
This dispenser was designed for a 19.5mm syringe, but it will also work for a 14.5mm syringe, just print another plunger. This plunger will also fit large syringes so only this can be printed.
UPD: added a little improvement (see photo) :)
