oh wow, I have added the ports on the back. You can see the seam where the holes are split which divides it into the top part which snaps on to the bottom. Easy to assemble as long as the latches do not break. I am trying my best to make the print possible with normal PLA and a 0.4mm nozzle size which currently should still be possible. I am really confident that the final product (which I am pretty close to ;3) should not be too difficult to print for the average user but I need to print it to judge that which hopefully happens this week as I will not be able to work on it next week :<
