GBA SP Battery Shim

This is a small shim spacer to use when installing a "MegaBat800 High Capacity Battery" for a Game Boy Advance SP, because the battery is a bit small for the gameboy battery space.

I didn't design this, I got the file from this link, that I got off of the website I bought the battery from:

Thought it would be easier/more convienient for this to be found on Thingiverse, instead of looking around for this link
