Toilet Paper Insert

Are your toilet paper rolls smooshed and smashed? No more thumping around the toilet paper holder, making a racket and waking your babies! The model has parameters within it for the inner diameter (post), outer diameter (cardboard tube), width/height (so that it hides inside your TP role) and the number of splines. I found that 15 is decently strong and smooth. If y'all want adjusted sizes, let me know and I can update the model with different parameters. I'm trying to rebuild in OpenSCAD, but my goodness, I have no idea what I'm doing… Pop one of these bad boys inside all your TP rolls for a smooth and satisfying pull of that TP. And without the noisy TP, nobody will ever know how many wipes it took!! Boost MeI like making silly but useful things, and am bad at modeling... filament is my greatest expense.
