Shopping bag handle

A handle that you can use for carrying up to SIX bags with only one hand!
The design is very sturdy and it has been tested via FEA in Inventor 2017 following the Galileo-Rankine-Navier criterion (every force applied on the hooks is 40 N and roughly corresponds to a 4 kg shopping bag). I used regular PLA to print it, so you don't need any fancy super strong material.
I recommend printing it with a good percentage of infill (I chose 50%) and at least a decent layer height (I chose 0,2 mm).
