Not too long ago, I came up with the idea of using 3D printed strap adjusters for prototype bags rather than constantly buying a new pack. A student workshop called the Alley, which I coach at, owns two Lulzbot Taz 6 printers. I used one of them to print off two strap adjusters that I found on Thingiverse.com. I used black PLA filament, and it took the printer about 30 minutes to print them both. Below are photos that I took of the printing and installment of the 3D printed strap adjusters.
Until Pick’n Run purchase its own 3D printer, the Alley’s 3D printer will be used in the meantime to print additional strap adjusters for future prototype bags.
