Increase your percentage of infill and this seems to fix the problem for me on increased tile size. I also had to monkey around with the size of the clip until I got it to work. Also there is a softer design available on Thingiverse (I didn’t make it) that can be experimented with and is less likely to snap features, but can hold better if oversized from your original 120%. Again experiment with the locks until you get the right size. I will provide the link to the soft clip.
