“Easy to build but very capable and handy DIY solder paste dispenser built mostly from cheap Ebay components and modules.
Already finished and nicely working solder paste dispenser. Powered with cheap ebay mini DC motor with gearbox (100RPM) and long M3 shaft secured by two axial bearings also from ebay. Body of both control box and dispenser is fully 3D printed. Accepts standard ebay 3ml luer lock syringes. Firmware supports dispensing speed configuration and also retraction to prevent leaks. Push button is available on the control box as well as on the handheld unit to be able to control the dispensing according to personal preferences.”
