Thetford 335 Porta Potti Chemical Storage Solution – PETG

Overview This custom 3D printed insert is designed specifically for the Thetford 335 Porta Potti, providing a convenient way to store your toilet chemicals directly inside the unit. The insert fits neatly within the internal cavity when the waste holding tank and flush tank are separated, making otherwise unused space functional and accessible.
