A cartridge assembly () of a 3D printer system for printing a plastic substance, such as a dough, comprises a refillable cartridge () and a punch-fill adapter () having a circumferential cutting edge () and being provided with a punch-fill connector () to form a manually releasable interconnection between the cartridge and the punch-fill adapter. When said interconnection is effective, the cartridge assembly is effective as a manual tool for punching, by means of said circumferential cutting edge, punched slices out of a supply slice of said plastic substance, and thereby for automatically inserting said punched slices into the inner space of the cartridge. Thanks to this punch-fill connector the manual (re)filling of the cartridge can be performed more easily and more reliably.
