I do not have an actual lego bat, so I made this based on pictures. I recently found out it has a tail, but this one does not, oh well. If you would like to add a tail, or change features, it's in TinkerCAD here, https://www.tinkercad.com/things/3xG2pyaKhhF-lego-bat/edit. If for some reason that doesn't work, its just called LEGO Bat on TinkerCAD. Additionally, as with my other Lego Compatible 3D files, you can tweek the "hole" to perfectly fit your Legos as per your printer. If you can't find it like that, search for my user name, Steampunker75 and you can find other Lego files I've created as well.
As with my other small Lego objects,
PRINT SLOW AND LOWER TEMPERATURE WITH LOTS OF FAN! Just thought I would make that part stand out in case you didn't want to read the top boring part.

I printed it in PLA, and it works great. Enjoy! :D
