That's awesome, I have a makita impact driver and need to create a adapter to fit it to a dewalt battery, are u able to make one I'll pay u for your design

it's already done and free!

Look It's not an adaptor itself, because it can not be removed. It's permanent change.

So you need the one called dewalt_battery_adaptor.stl (it's for the 20Vmax, not the old 18V).

You print it. Than you install any thin metal plate in both slots: I use metal straps or washer. Than you connect two wires on them and plug the wires on the tool. Than you can glue or screw it on your tool.

N.B. As I don't use dewalt really often I know it is a little hard to slide on the battery at first. The trick is to heat it just a little to soften it. (I use a heat gun or boiling water. Than slide it on the battery and let it cool.

And that's it!

is there an adaptor that you have that you can use dewalt battery on makita cordless saw?

Yes, use dewalt one and screw/glue it on any tool you want.

ill print that up and try it out. ill post pictures after

Last time i printed dewalt one, it was a little tight. Print it directly, but once printed, heat it before clipping a battery on it. Put it into boiling water or heat it with a heat gun. Then let it cool on the battery. This should work perfectly.

You show a ryobi nailer, but I don't see an stl file for it. Do you have one? Would love to have one. All my tools are Makita lxt except the ryobi nailer. Would love to use my makita batteries!

So you need makita battery adaptor. Nothing about ryobi! You can glue or srcew the makita battery adaptor directly on your ryobi tool.

Tried the bosch adapter, works ok, thanks.
If the base plate would be longer and wider, it would be easy to fix to old batteries.
I have hitachy and will edit this to have 7 x 11 base

A small suggestion to improve your design is to make rounded corners on selected corners, just like on this Milwaukee battery adapter:
With screw holes: https://www.thingiverse.com/thing:655904
Without screw holes: https://www.thingiverse.com/thing:216786

Just keep the sharp edges on the sides facing the power tool and round the edges on the other side facing the battery and also the edges where you slide in the battery. Just round the edges you can see has been rounded on the Milwaukee design and keep the other edges sharp and unchanged.

Great project.
But you misspelled Bosch wrong every time. You wrote Bosh instead in both the title, the description text and the filename.
You should probably edit that to Bosch everywhere, so this design will show up when people search for Bosch.

You're right!!

Now it is fixed!



I can see you just uploaded a new 18v_boshv3.stl, probably just to correct the spelling error? But it's still spelled without a 'c' in the filename.

I do have a adhd... I sometimes feel so stupid.

But I changed the file because it was a little too tight i scaled it up.

I'm fixing it. and for screwing holes and round corners, it is a very good idea, I will propbably change it soon

thanks again!
