2 versions, a single battery and a triple battery version. Prints vertically, no supports

Important note on scaling

As the fit of the battery is so precise I would advise printing the single version first to test fit. 

Mine were printed at 100% on a Prusa mk2s. However you might need to scale up on your printer
 

** Remember to de-burr any edges, as this will affect the fit

Note that I printed all of mine in PETg, which is more flexible than PLA, and therefore you may need to upscale slightly to achieve a good fit in PLA
