Gear for going hiking and camping is often prohibitively expensive, and a pack, though necessary, can cost a lot of money. With this set that's entirely optimized for 3D printing without supports (Autodesk Fusion 360 is perfect for creating functional, dimensionally accurate end-use products like this—get it here! [affiliate links]) you can refurbish an old pack with worn out buckles and straps—I bought mine used for $20 (USD) and fixed it up so it works perfectly for my needs. Even if you have a good, relatively new backpack or hiking pack, you can personalize it with these items and some paracord of your choice.
These items are included in the set:
- Zipper Pull (3 different sizes depending on the diameter of the cord you're using: 3 mm, 4 mm, and 5 mm)
- Cord Lock (two options: a printed spring mechanism or using a spare spring, like one from a pen, that you already have)
- Strap Tightener (sized for a 25 mm wide strap; scale as needed)
- Squeeze Buckle
It should be pretty easy to see how each item works. There are a few special instructions: for the Zipper Pull, cut your desired length of paracord (100-120 mm is perfect) and feed it through the loop on the zipper mechanism already attached to your backpack. Using a lighter, heat the ends of the paracord until they're melted and push both ends into the holes in the printed zipper pull, making sure they fuse with each other and the plastic before hardening. If you're using your own spring for the cord lock, you'll need to measure and cut 2 10 mm lengths and fasten them to the indentations in the model.
Enjoy your newly enlivened hiking pack or backpack! Whenever possible, you should try to find and fix up used items instead of new ones—it'll be good for the environment and for your wallet.
*Note: the Buckle_Female file is slightly different from the one in the images; the bridge around which the strap wraps is expanded to be the same size as the one on the Buckle_Male file.
