In this video I will show you how you can use one tool battery on any brand of tool! By creating a universal tool battery system, now you can save yourself hundreds of dollars from investing in batteries and chargers from different brands and consolidate your tool batteries because they are now interchangeable!
To do this, you will need a 3D printer, the appropriate electrical contacts, and some wire at minimum. I've made my design files available on Thingiverse and you can find them here so you don't have to design it yourself if you are looking for a Milwaukee M12 to Makita CXT adapter.

I will likely be creating more adapters in the near future, so you should definitely hit the subscribe button if you are looking for a different combination!
For this particular adapter, you will also need the following:
► M2x10mm Socket Head Cap Screws
► M2 Washers (7mm OD)
► M2 Nyloc Nuts
The battery contacts on the Makita adapter are:
► digikey.ca/product-detail/en/keystone-electronics/5209/36-5209-ND/299941
The battery contacts on the Milwaukee adapter are:
► digikey.ca/product-detail/en/keystone-electronics/1221/36-1221-ND/4499215
► The ring terminals are regular insulated #6 ring terminals, and I believe I used 16AWG wire...
► The resistor was a 10K 1/2W resistor from my tool box :)
If you want to make an adapter for a different set of tools and batteries, try your hand at 3D modelling with a free version of Autodesk Fusion 360! An incredible tool to get for free and you can find it here:
► autodesk.ca/en/campaigns/fusion-360-for-hobbyists
You may also find the files you need already designed for your on websites like:
► thingiverse.com
► grabcad.com
People upload thousands of designs and you might save yourself a lot of time using someone else's design!
