I've finished my work on the fifth prototype today, and although I'm not 100% happy, it's definitely a step in the right direction, and I've learned a a whole lot - especially in regards to anger-management... 🥲
This has been the first prototype which I've fabricated out of "real" materials, and I've managed to hit almost all of my set measurements to the T; I only have to add a millimeter here-and-there, as I've underestimated the tension on the fabric once it gets sewn together (it shrinks a bit), but other then that my theory made it through practice.
There's a few changes I'll make going forward with prototype #6, I.e: I'll work on adding side pockets, enlarge the curves and make them smoother, probably change the Pack's dimensions (I'd like it to be a bit more compact), and - most likely - I'll add Velcro patches on the front for added modularity, but overall I'm on track.
Anyways... I'd be happy to hear some input!
