Abstract: A portable roller press having removable cartridge rollers provides for reconfiguration through exchange of the cartridge. The die press housing includes a shell having an opening configured to receive a cartridge having one or more rollers, which may be configured to provide a desired operation. The housing can include a handle that is configured to couple with a connector on the cartridge to transfer rotational forces to the cartridge rollers. The housing can also include a base having a surface substantially aligned with a working area of the cartridge when it is inserted into the housing. One or more extendable surfaces can be coupled to the housing at the base and can be extended to increase the surface of the base. The extendable surfaces can each have one or more feet on the underside to support the housing.
