The track supports that come with the PicassoTile sets often break when removing the tracks. The little plastic nubs just snap. Especially when 3 year-olds are using them.

I designed this to be a bit easier to remove the tracks from. The nubs are slightly narrower so the pieces slide on and off a little better. The nubs are also slightly taller so you can push on them to help release the tracks.
