Flux/solder paste syringe extruder

thingiverse

I made a clone of a very handy extruder, which I bought on Aliexpress. Needed hardware: M6x95, M3x16 and M3x12 screws, two M3 nuts (I prefer one of them with nylon insert, self locking type) and one specific nut, it's 10 mm in diameter, 12 mm height, and it's M6 thread cross the diameter. Chinese extruder uses same type, I found them in my box with nuts and bolts, I did not buy it. Connecting part I suggest to print horisontally, using support, for better strength, that's why I did it separate from the ring.
