Gridfinity AA Battery Container Magnetic

One of the holes is not perfectly round and possibly won't fit a rechargeable. If you know which one exactly, please let me know, I cannot tell from looking at the tinkercad design :( https://www.tinkercad.com/things/d9rNKXfs0aS-gridfinity-aa-battery-holder-magnetic - don't judge me after looking at it ;-) The original a) doesn't have magnet holes and b) my rechargeables wouldn't fit, so I added the magnet holes by replacing the bottom 5mm with a variant that also has a hole bridging fix, and increasing the top hole diameter for the batteries themselves. In the picture, the object on the right is the original holder, this is how far the batteries fit in without pushing. The left cube is my remix.
