Thick toilet paper spindle

thingiverse

This toilet paper spindle (roller, axle, whatever you call it) is designed to fit the core of the toilet paper roll snugly, so that it is centered and rotates smoothly rather than wobbling. In particular, my toilet paper holder is partly inset into the wall, and this prevents the roll from sticking against the bottom and being hard to pull. You may need to customize it to fit your holder (and spring); I don't know how standard the particular dimensions of these things are. If you do, I recommend downloading the file; I haven't polished it up for Customizer, and in the file there is an option to preview the fit of the two halves to make sure your changes will work. The spring I used is specified as 23/32" diameter by 3 1/2" long (18.2 mm by 88.9 mm). The spring length can be modified in the `.scad` file. Remember that the spring should be preloaded (the length of the cavity in the spindle is somewhat shorter than the actual uncompressed length of the spring), or it will fall out too easily.
