Description: This 3D printed battery connector is for a very common cheap power tool battery sold in Europe. It goes by the brand Parkside Tools here and is sold by Lidl. It may be available in some countries under a different brand. There are quite a lot of battery connector designs on Thingiverse, but they all seemed quite complicated. So I decided to make a very minimalist one that prints fast (12 minutes), fits snugly and just does the job. You can find a longer video showing the gluing process here:- youtube.com/watch?v=0oBbF3bcDck Note that some battery packs do not have internal overdischarge protection, so care should be taken to avoid discharging the packs below around 3V per cell. For an 18/20V pack that's usually around 15V. The connection system is actually pretty solid, so with good quality plated copper spade crimps it should handle a decent amount of current, but don't push it too far. I'd envisage this adaptor being used for things like lights and USB chargers. Adding an inline fuse is always a good idea. Here's the openscad script. Just copy and paste the text below into the openscad freeware and then build and save the STL file. I'm doing it as a script so you can hack it to fit other battery systems. //Parkside battery mini adaptor //Use with two male spade crimps difference(){ union(){ //main block cube([46,20,10]); } //side slides translate([-1,5,5]) cube([6,21,6]); translate([41,5,5]) cube([6,21,6]); translate([4,5,-1]) cube([3.5,20,12]); translate([38.5,5,-1]) cube([3.5,20,12]); //Terminal cutouts translate([8.5,1,1]) cube([6,18,10]); translate([31.5,1,1]) cube([6,18,10]); //terminal slots translate([10.5,17,1]) cube([2,10,10]); translate([33.5,17,1]) cube([2,10,10]); //cable slots translate([10,-1,4]) cube([3,10,10]); translate([33,-1,4]) cube([3,10,10]); //plastic and time saver translate([15.5,1,1]) cube([15,18,10]); }
