New Nintendo 3DS XL Extended Battery Cover

I was so tired of not seeing any back plates for the New 3DS XL if you wanted to use the Extended Battery (Cameron Sino battery, it's on Amazon) so I made one. I went and downloaded a back plate that was made by gmoff01 on thingiverse, and kept putting it and some structures together, going through a total of 10 iterations, before it worked. Now this backplate does leave around 4mm of space between the battery and the plate, so I recommend using something to fill it (I used a 2mm thermal pad, cut it into 2, and stacked them on one another). I also included on a separate plate a spacer, made by Wurmatron on printables, as to connect the extended battery to the port. If you want to change this or improve the design, you're welcome to!

Update: I have revised this backplate so that you can use some free space to carry up to 3 ds/3ds cartridges with you

Here's a link to where I bought the battery: https://www.amazon.com/5000mAh-Extended-Battery-Nintendo-CTR-001-MIN-CTR-001/dp/B005NJ2UEW/ref=sr_1_4?crid=3G2W25CAORS8D&dib=eyJ2IjoiMSJ9.p3Z5U0ZDQXmXyF1-Spycz5mMPEdNJc9xvpfqkgUC5IJdkACs5O2UWK8OINmaaiDGrQB9kxfY8gtdZDcQ59-f3CK-XihoXUaZDdVzOs6BrgAum76V0T4KcY16qDEEB3E505VDKgFsn4_X9xrc1_Y5uH_wKn2YsTmMPCiw974hUhlVwDLy6cxC5CnHSmg2X9GVFITvxH259esZrKnDT7gc3J_kt8xF0V7z57fVHNYq-ko.B-U-JW9syEi3q331EFlgy5s1vCqRwWdfc0Z1TZcl81c&dib_tag=se&keywords=3ds+battery+upgrade&qid=1783534609&sprefix=3ds+ba%2Caps%2C198&sr=8-4
