Threw this together to replace my long used, but finally worn out, soda bottle TP filter that I use to filter freeze dryer pump oil for particulates.

Remove the cardboard tube from a roll of TP, and squish/cram it into the center cavity.*
Then screw your wide mouth mason jar filled with oil onto the open end,
an empty wide mouth mason jar onto the ‘grid’ end,
and invert the assembly while it SLOOOOOWLY filters the oil into the bottom jar.

I've included an optional square base if you have tipping problems because of the height.
I've also included an optional ‘cover’ that you can screw onto the oil side, incase you also live in Texas and hate clouds of fruit flies that seem to love freeze dryer pump oil.

Printed this on an X1 with baseplate supports to prevent warping. YMMV.

* You can go a few YEARS on a single roll of TP.
