Toilet Paper cap

if you remove the cardboard inside a TP roll you can pull the wipes from the center .. this cap makes it nicer and protects it from dirt. 

You can print two, put a paperboard around the roll and  caps on the ends  - so you get a nice casing.  Or roll some parcel tape around.

For keeping TP in your car or workbench. 

I am using this with bamboo wipes for cleaning my print bed with IPA
