Solderpaste And Flux Gun

thingiverse

This is my version of a 3D printable solder paste and flux gun. I've posted a video on YouTube that shows how to assemble this solder-paste gun: https://youtu.be/BK9-DYdfV4c. A wall mount bracket for this gun can be found here on my Thingiverse page: https://www.thingiverse.com/thing:3143835. If you find this design very helpful or wish to support me, you can buy me a cup of coffee, which helps keep my brain active so I can create new stuff. Please consider using this link: <a href="https://www.buymeacoffee.com/Mb1vZjXUG" target="_blank"><img src="https://bmc-cdn.nyc3.digitaloceanspaces.com/BMC-button-images/custom_images/black_img.png" alt="Buy Me A Coffee" style="height: auto !important;width: auto !important;" ></a>. The same front adapter plate can be used for both the small and big syringe, but it's designed to fit the big syringe. I'll make an adapter that fits the small syringe later if anyone wants this. I've tested it with both syringes, using solder-paste and flux, and it works perfectly with both. However, you'll need to use more force to press the solder-paste out, especially when it hasn't been used for a while, so be careful with the pressure. This design was printed in Max PLA, which should be stronger than normal PLA. I recommend printing this in ABS or at least printing the push rod in ABS. I'm not sure if it would work with PETG since it tends to be somewhat flexible. Parts needed to assemble this gun include: * 5 M4 nuts * 3 M4 bolts, 25mm long * 2 M4 bolts, 12mm long * 1 M4 bolt, 20mm long * 1 M3 bolt, 12mm long * A stiffer spring (you'll need to experiment with this) * A softer spring (you'll need to experiment with this) The length of the springs will depend on the type you use, so again, you'll need to experiment with this. Sorry for not being able to give more specific notes about this. I used two springs from a large collection I've gathered over the years. Maybe you can do the same.
