Model's purpose & origin
This is v1 of my shopping bag holder to help people carry bags more easily, This model was created after i hurt my fingers trying to carry multiple bags (one of them ripped and the items fall on my leg XD)
Print instruction
as this is a model that is made to carry heavy bags you really need to have a high infill% and a strong pattern (so not Lighting or adaptive cubic or any of those kind of infills)
i printed a 50% infill grid pattern one and from my tests it is definitely able to carry some weight without snapping off, all you need is to choose a solid infill pattern and a % between 30-50
