The new Battery Inserts are designed to fit in any 1x1 MagSquare, shallow or deep it doesn't matter.

The battery inserts currently support AA or AAA batteries. We could support more in the future if people are interested.

The middle of each insert as cut outs so you can fit your fingers in to pull the insert out even if they are full of batteries.

They are super easy print, with not supports. See the last picture for print orientation.

Make sure to check out the MagSquares Collection to see a full list of MagSquares currently available.
