Toiletpaper Roll Insert

Sick of toilet paper rolls going clunk clunk and tearing too soon because the kids jumped on the pack of rolls and squashed them?
Then print off this plastic insert which forces the roll to maintain it's circular shape. Stuff with a scented cloth and you have an air freshener too. You might need to resize depending on the brand you usually get. I printed mine off with no supports, and it was usable.
