Makita Battery Soldering Iron Adapter

thingiverse

I needed to use my trusty Weller soldering iron in places away from a wall socket. Instead of buying another gas or battery-powered soldering iron that likely had a small battery, I came up with this little project to take advantage of my Makita LXT 18V battery. This is a more complex project that may not fully meet your requirements, but the parts can be useful. The first challenge was to transform my 18V battery voltage to 24V or 28V that my Weller soldering iron required. I ended up using a buck booster step-up module. There are several different modules on the market. The one I used (see included specs sheet) met the power rating and specifications I needed. The buck booster together with a push button switch and panel mount socket were integrated into a 3D printed box designed to fit my Makita LXT 18V battery. See included photos. For added robustness, this has been printed in PETG. Other filament types can also be used. My print is made in PETG 1.75mm 3DFillies black filament with 0.2mm layer height and 25% infill on a PRUSA I3 MK3S printer. I hope you find this print useful, too.
