Spare toilet paper roll holder. Two pieces, simply split and rotate the lid.
Fits standard rolls. If you get oversize ones then you might need to scale up the model 10-15% to fit the diameter.
Try not to get too much first layer squish so that the lid pattern remains. I had too much on my first print shown here, but reduced it on later ones and it looks good.
