Hitachi circular saw external power adapter

thingiverse

This adapter lets you run the excellent Hitachi C18DBAL deep cut saw using external power (like a Chargery S1200). Great if you don't want to keep around yet another set of batteries and charger. You need some brass strips (can get 0.4mm thick ones @ Lowes in hardware aisle) and patience to bend the spring contacts. Power cord is 3m of 14 AWG wire. No load power draw is ~120W. Don't know what peak power is, but heard these battery packs could go up to 30A, so definitely should print this with a high temperature resistant plastic like ABS. There's lots of other power tools out there that could benefit from this, so I would like to make this a parametric model like OpenSCAD. But I don't know how simple it is to support all the battery pack geometries out there.
