Hi guys,

I know there's a lot of guys on here with Ozito tools and batteries. I've also accumulated quite a few myself but there's some pretty nice looking Ryobi 36V tools too and I didn't want to have to buy new batteries so I've made an adapter for 2x Ozito PXC 18V batteries into a Ryobi 36V battery.

I haven't wired mine up yet but I've done a test fit and it fits perfectly into the Ryobi tool. I'll try and wire it up over the next couple of days and post the results.

I don't know if I need to say this but please don't try and put this on a Ryobi 36V charger, it will likely fry the Ozito batteries and might cause a fire. You should charge the Ozito batteries separately on their own 18V chargers.

Take a look at the design here and feel free to post comments below: https://makerworld.com/en/models/845391#profileId-792429

    You Sir, are a scholar and a gentleman.
    Good day to you. Tut-taa

    When I saw the design on printables, I knew it was you. Looks perfect. Where is the best place to get the wire?

    • gyrex on 04/12/2024 - 10:41

      I'm going to use the 7.5A wire from Jaycar. I'll let you know how it goes.

    How great is 3d printing

      3D printing is awesome… but when it really gets "great" is when you can start designing your own shit as well. It's fine for finding other people's files and just printing shit for the sake of printing shit, but often there is a niche thing you need for something at home or work and literally no one has a file for it and you design it from scratch and dont have to pay for a whole new *insert broken thing* for the sake of $0.20 in filament and an hour or two of CAD…

      At work I am always on CAD designing shit for the workshop or for once off tools and adapters for cars instead of paying some stealership hundreds or thousands for a "cam locking tool" or some random trim clip/retainer nut.

        i wish i had the focus to sit through an hour or two class and actually learning something a bit better than tinkercad.
        have fixed a few things around the house with custom hacks / modified stls to make it work for me - but usually end up having to do 3-5 revisions until i get to THE one.

        everyone else on youtube seems to be able to just smash out a design in no time and then print it as the final copy ready to bang in first go

        i find even in tinkercad sometimes what should be easy manipulation is a pain in the butt - but i guess to be fair, its easy, aimed at kids, and requires no download.

          Keep at it, comes with practise to be able to know tolerances etc. right the first time. I think I am quite good with CAD but I still find I sometimes have to do a few revisions on prints. Often what I do is print just the part with tolerances required to fit something else first, make sure it works.

          Give Onshape a go. I had no CAD experience at all and I learnt it myself after watching a few videos and their community support is superb.

    This is amazing, thanks gyrex!

  • damonop on 04/12/2024 - 09:21

    I used that print to resurrect a $10 Ryobi 36v mower I got at the tip. Works really well with 2x ozito batteries. Use decent gauge wire connecting the batteries. Check with multimeter that you have ~36-38v beforehand

    • gyrex on 04/12/2024 - 10:42

      Used which print? Is there already an adapter out there because I couldn't find one for the life of me!

        This is the one I printed. Very similar to yours, I thought it was actually the same design

        I've been using it for a couple months on my mower

        • gyrex on 04/12/2024 - 11:08

          Oh no, I had no idea this existed! I wouldn't have spent all that time designing one if there was one already available… Looks like a nice design too.

          Also, how do you get an Ozito 36V mower from the tip? Do people just dump them there?

          • pegaxs on 04/12/2024 - 11:12

            @gyrex: In my area, there were about 3 or 4 of them out for hard garbage pick up (Ozito + other brands). One guy even left the batteries out (no doubt they would have been knaffed), so it's not hard to believe they would turn up at the tip from time to time.

            • gyrex on 04/12/2024 - 12:28

              @pegaxs: That's an incredible find! Where do you live out of interest? I'd suspect that most of the failures are probably battery related since most of the 36V tools use brushless motors and would be quite reliable. I might head to the tip and ask the guys there.

                @gyrex: It was just laying at the entrance with jo batteries or charger, so the lady said I could have for $10. I did anticipate id be able to make a ozito to Ryobi adapter to get it working. Without a charger or battery, most people let these go for free

  • Boioioioi on 04/12/2024 - 11:25

    Thanks mate! What spade terminals are you using?

    I have made my own for Ozito battery to work with Aldi tools, wanting to make one for black & decker and snap on as well. I've been having challenges on the part that connects to the Ozito battery, my terminals dont stay in very well. I might download yours and have a play around with it.

  • Boioioioi on 04/12/2024 - 11:45

    Any chance you could share your file as a .stp or another file that can be opened in cad? I'd love to reuse some of the Ozito side of things in making adapters for other brands

      I design everything in Onshape and they're public documents and you can modify them there or export them to your heart's content. Here's a link to the Ozito battery mount I've designed: https://cad.onshape.com/documents/9c8d0ffe14128fd5ebd48220/w…

      • Boioioioi on 04/12/2024 - 21:03

        Legend! Thanks so much

        • gyrex on 05/12/2024 - 03:38

          No worries! Out of interest, what brand did you want to adapt?

          • Boioioioi on 05/12/2024 - 07:43

            @gyrex: I've got a black and decker vacuum that uses their brand power tool batteries that I want to adapt.

            I've also got a few ALDI tools with broken batteries I want to do.

            Finally I've also got a snap on brand impact driver I want to adapt

    Just an update. I wired it all up and made some changes to the design along the way. Fits and works perfectly! I added some photos showing the series wiring required.

  • Brodo Faggins on 09/12/2024 - 01:36

    Make a youtube channel pls 👍

    • gyrex on 09/12/2024 - 20:44

      I'm not interesting enough to make a YouTube channel 🤣

      • Brodo Faggins on 10/12/2024 - 14:48

        Don't have to show your face or even talk 🤣 Just stuff like BTS or documenting your DIY process start/finish! hahah

  • a1234my on 20/12/2024 - 10:31

    Try to do the other way round!! Roybi to ozito.
    Can imagine the size
