28BYJ-48 Syringe Pump / Paste Extruder

thingiverse

I had this stepper motor in my house and I didn´t know what to do with it so I decided to make a syringe pump as I like to call it, to use with solder paste. Since I didn't know how to get a even flow of the paste I design this little tool. It works with a stepper motor, this motor move back and forward pushing the air out of the syringe to another syringe with to tact switches (Forward, Backward) in order to activate the motor. Probably I'm not being clear on the explanation but, I'll be posting news, updates. All comments will be highly appreciated. UPDATE: Dec/13/2015 17:45 = Here you have thelink for all the STL and original files.https://drive.google.com/open?id=0B7dtMeeMPK5rfjcyQl9yN09IMC1pZm5GZ0NvZGg1ZW12anlyczRuNEVUWWVOU2dvUWQ1bGM UPDATE: Nov/12/2014 0:03 = I have uploaded some pictures of the printed parts. Still one missing, I have to print it out.

I downloaded but, is had a problem with various softwares to open it. I have repaired the mount and uploaded. Instructions Bill of materials 2) x 3 mm smooth rod. (136 mm long) 1) x 3 mm threaded rod. (136 mm long) 1) x 28BYJ-48 Stepper Motor (I'm using the 5V one). 1) x Set of plastic parts 1) x 5 cc Syringe OPTIONAL A table to place the pump so it doesn't move. ASSEMBLING INSTRUCTIONS Here you'll find a very useful video of how to assemble the pump.https://www.youtube.com/watch?v=M6tPrioTTM4 I haven't tested the pump yet, but I'll be posting the results of it. I did a little search on the web and I think you can use a 10cc syringe without having to modify the files or even filing the plastic parts.
