There are more bag handles on makerworld, created like hooks for carrying more bags at once. But I created model for one high-weight bag, when yours fingers are “crying” because the handles of your bag trying to cut your fingers. Using this handle yours hands will be more comfy ;-)
Next positivum before hook-handles is that your bag is not too low terrain ;-)
I try print three versions. 20mm is too small, 35mm is too big. This is 30mm version. Place for fingers is 92mm (length). Optimal for me, maybe fine for you too. You can scale it as you wish (maybe lower the Z scale by 2-3mm). For pretty/petite women (sorry for my poor english) maybe You can shrink length by 5mm (?).
I positioned the model 0.2mm (one layer) under the bed because of overhang. Do not forget for that, when You repositioning/rescalling it. Used strong profile, with small changes - 5 perimeters for walls, 5 top and bottom shell layers.

I have alternate version, if You have problem with the bag handles to stay in place, maybe this can be for You:
