3D model of a jar opener. It works for both types of jars: screw-on lids and pry-off lids. For screw-on lids, the model has inner spikes that help hold the lid more securely while opening the jar. It also works well with different lid sizes.
The ergonomic handle is comfortable to hold and has separate spaces for fingers. The edges are rounded to make it more comfortable and as safe as possible for the user. The finger spaces are also designed on the second handle, so the user can choose where to place their thumb.
The jar opener is 20 cm long, which means it is easy to store at home and does not require any extra storage space
