Digital Caliper Battery cover

I lost my original cover and printed the cover from the original project https://www.thingiverse.com/thing:3463470. I found the size to be great, but my battery was not secured enough and the calipers would turn off in the middle of measuring.

So I designed this cover to press the battery into place so that the calipers would not turn off. I also added some grip to the top to aid in removing the cover, as I found the smooth top to be far too hard for me to remove.

I did not use the switch with this cover, you may need to try the cover and switch together to see if they work.

This is not perfect but it works for me. I designed this in FreeCAD and I am still teaching myself how to use the program. This is my first posted project so any critique would be welcome. I have included the FreeCAD file if you want to modify this yourself.

Print the cover vertical for best results. I used PETG (because it was already loaded in the machine), but I'm sure PLA will work.
