About this 3D model

This is a jar opener designed for jar lids from 85mm to 95mm. Using this jar opener makes it much easier to open the jar. The handles will touch before the part cracks. it has inherent stoppers. Print with PLA, with 7 to 9 perimeters. If you put too many perimeters it may become brittle so I recommend not going over 9. here's some scaling factors: Scale (%) Approx. Lid Range (mm) Typical Use Case 70% 60 – 67 mm Small spice jars 75% 64 – 71 mm Condiment jars 80% 68 – 76 mm Medium jars 85% 72 – 81 mm Standard food jars 90% 77 – 86 mm Small mason jars 100% 85 – 95 mm Standard large jars (default) 105% 89 – 100 mm Large food jars 110% 94 – 105 mm Extra-large jars
