It's time for another video with an openscad script for creating battery connectors for common battery packs. In this case, i'm not sure how come this is around the world. It's the little parkside 20 volt battery. Well, it's an 18 volt battery in any other manufacturer, and i did look online and saw that uh there were thingiverse adapters for it that went the full hog.

They covered the whole thing over. They even went under the latch, but i thought that's going to take ages to print. I wanted something simple, so i rattled up a basic outline of a connect that went on like this and take spade connectors and the end result is actually i ended up, making it shorter the it uses, standard, speed, connectors like these that are crimped on, and then The assembly is pressed in with those crimps on it and then their hot melt, glued in place and i'll show you the whole process of making this. So, first of all, you want to take the script down below in the description and you want to print it off, and this prints fast.

This takes about 12 minutes to print once you've got it use a file to clean the elephant's foot bits off this, because it's a very precise fit once it's fouled down, i tend to squish the material down the first layer just to get a good adhesion, so The elephant's foot is when it just splays out slightly outside and you get a slight sort of lip around the edge. So once that's off, and it's going in neatly like that, get your pre-crimped terminals, i chose to use the standard, uh sort of red crimps. This of low current ones and making sure the other end of the cable is not shorting out put the red to the positive, as you would expect shove it in, because it goes in nicely between the contacts and the black was in the other one and again Shove it in so it slides into the contacts and there's a precaution just to make sure everything's snug just seat everything down. So it's nice and tight then carefully get the glue.

I gun a glue gun here and smooth those into place, noting that you don't want to put too much in too much runny glue, definitely not resin. In case you actually end up gluing it permanently into the battery pack. I've just actually melted that away, but that's all right, it's fine! It's going to be super and let it cool, and while it's cooling, while it's just cooling i'll, show you the other one i've made the script is also included down below a lot trickier. I wanted to make one for ryobi, which is definitely around the world uh here's the version i did for the iob battery.

It's again, it's some it's less than 15 minutes to print this very quick. It's got the polarity marks on the top and when it's placed on over the top of the battery port, you can then take the same speed, connectors and you can shove them down here and down here. So i shall shove them in and inside. Well i'll show you afterwards there's a little uh packer that just presses those onto the contacts once it's in, and this is where it gets a bit ugly once it is in you, then hot melt gloom in place, and that does make this look like a very, Very ugly connector, now, if we look inside, if i zoom down, you can see how i actually the contacts here which do make a good contact.

They're stepped out. They've got this little lip here to actually press it in. This was all done by trial and error. It only took a few goes.

It was pretty good, but once you've got that hot melt glued - and this is where really it would have been nice having little ports on top that the hot melt glue and actually supported these crimps better. But as it is uh, i just had to glue them like this, because it prints flat to get a nice clean interior as it's printing up the way and that kind of makes it harder to build ports out underneath without lots of sort of structural support. Underneath uh that gets cleaned off later, but i'll maybe try that later on. But the end result is that uh you get a connector that just presses snugly on and makes a decent connection onto those air contacts.

This one is still hot. I shall uh i'll, let it cool down and i'll be back in a moment a short time later. The glue is now set and you can pull your connector out here. It is with its two solid spade connectors that make a very good connection when they go in.

Let's check that, let's get the metering set to 20 volts because uh this is a well set to 200 volts, actually because 20 volts might be too low. If this has got a decent charge in it and without shorting the battery pack out, let's see if we're getting a good connection which we are getting a good connection, it's a great connection. 20.2 volts at your disposal uh. So that's actually a pretty good result.

It makes a nice solid connection with brazilian, so let me know what you think: try the script down below and uh tell me how they work out for you also. Let me know if this format here keep in mind. It's only going to take about like 12 minutes to print this, but let me know if it fits a similar battery under a different name or if like well, you know what the manufacturers are like. They tend to like move the slots about a bit uh just to try and stop people using their batteries and other products, but yeah.

Let me know what you think: the scripts are down below in the description.
