My ladder buckles on my backpack broke, amazon would not replace the backpack but gave me a refund. I didn’t want to throw away the backpack so I looked around for a replacement part, but ended up designing my own.

I will try the buckles on my daily commute and report/refine with the results.

It ended breaking after about 3 Months, so I remixed it for one of the challenges. I basically doubled the z-height and it’s holding up for more than a year now.

So: this version is still good for light duty, if you’re carrying a heavy backpack, go for the remix
