Net Design Four

I decided to research into handles in the carriers, as I was unsure about the strength of the design I have already. And I found a slotting technique that worked well, and so focused on that for this design. 

I want to keep the design very simple, as I want to keep the pricing down. I want to keep the printing to a minimum to keep everything as cheap and environmentally friendly as possible. I have also took out the cuttings from the sides also for costing purposes - as I already have quite a bit of laser cutting. But also for strength purposes, as six bottles are very heavy, it needs all the support it can get.
