Ikea made a toilet paper holder under the name LILLASJON that has a barrel surrounding the roll, with a shelf insert on the top. Big box stores that sell “jumbo” rolls in bulk are a touch oversized for this setup, which required removing or tilting the lid until enough had been removed from the roll to allow for it to sit flush again.
This lift adds 10mm to that shelf, giving clearance for those jumbo rolls.
