Hitachi circular saw external power adapter

thingiverse

This adapter allows you to run the outstanding Hitachi C18DBAL deep cut saw using external power, just like a high-performance Chargery S1200. It's ideal if you prefer not to carry around another set of batteries and charger. To get started, you'll need some brass strips (you can find 0.4mm thick ones at Lowes in the hardware aisle) and some patience to bend the spring contacts into place. The power cord is made from 3m of high-quality 14 AWG wire. Under no load conditions, this adapter draws approximately 120W of power. As for peak power draw, it's difficult to say, but with battery packs that can deliver up to 30A, it's clear that you'll want to print this adapter using a high-temperature resistant plastic like ABS. There are many other power tools out there that could benefit from this kind of adapter, which is why I'm eager to create a parametric model similar to OpenSCAD. However, I'm not sure how straightforward it will be to support all the different battery pack geometries available on the market.
