1. An ink cartridge, comprising: a single cast reservoir portion of a first polymer configuration, the reservoir portion including a bottom wall and raised walls that extend up to a circumferential top edge, the raised walls including a front wall, a back wall and two side walls;a straight, rectangular latch handle protruding from the back wall; anda single cast lid attached to the top edge, of a second polymer configuration that has a lower melt flow rate than the first polymer configuration; wherein the second polymer configuration is non-reactive with ink. 2. The ink cartridge of claim 1 wherein the second polymer configuration has a higher impact strength than the first polymer configuration. 3. The ink cartridge of claim 1 wherein the reservoir portion includes a free ink chamber and a foam chamber. 4. An ink cartridge, comprising: a single cast reservoir portion of a first polymer configuration, the reservoir portion including a bottom wall and raised walls that extend up to a circumferential top edge, the raised walls including a front wall, a back wall and two side walls;a straight, rectangular latch handle protruding from the back wall; anda single cast lid attached to the top edge, of a second polymer configuration that is stronger than the first polymer configuration;wherein the reservoir portion further comprises a separation wall, wherein a top edge of the separation wall is distanced from the lid, with a fluid exchange port disposed between the top edge of the separation wall and the lid; and wherein the lid includes at least one anchor which is configured to: protrude downwards from the base of the lid to anchor the lid to the reservoir portion;press fit against the back wall and the separation wall; andhas a main body and wings perpendicular to the main body, wherein edges of the wings slope downwards into a retention profile. 5. The ink cartridge of claim 4, wherein the lid further includes: a foam chamber retention profile to fit the lid to the reservoir portion, wherein the anchor is higher than the foam chamber retention profile. 6. The ink cartridge of claim 5 wherein the anchor is flush with the foam chamber retention profile. 7. The ink cartridge of claim 4 wherein the lid includes foam retention ribs, and the anchor is higher than the foam retention ribs. 8. The ink cartridge of claim 1 wherein the cartridge includes at least 11 grams of pigment ink. 9. The ink cartridge of claim 1 wherein the polymers are polypropylene. 10. The ink cartridge of claim 1 wherein the front and back wall include a mold parting line over the middle along the height of the wall. 11. The ink cartridge of claim 1 wherein a radius between the latch handle and the front wall is at least 0.23 millimeters. 12. The ink cartridge of claim 1 wherein a radius between the side wall and the front or back wall is at least 0.8 millimeters. 13. The ink cartridge of claim 1, wherein the front wall, the back wall and the two side walls are connected with corner fillets which improve strength of the first polymer configuration. 14. The ink cartridge of claim 1, wherein the lid extends to, but does not protrude from, the circumferential top edge of the reservoir portion. 15. The ink cartridge of claim 1, wherein the reservoir portion further comprises a separation wall, wherein a top edge of the separation wall is distanced from the lid, with a fluid exchange port disposed between the top edge of the separation wall and the lid. 16. The ink cartridge of claim 1, wherein the latch handle is attached to the back wall via a live hinge. 17. The ink cartridge of claim 1, wherein the latch handle has an angle of between 15 and 30 degrees with respect to the back wall.
