This is the second version of this tippet holder. The first one had a locking knob while this one is threaded making it much easier to use and it's more durable. I also added two more styles for attaching to other packs. There are three options total. 1. The basic version that slips through and existing slot like on my fishpond pack. 2. A horizontal option like the basic model but with a loop for a carabiner/parachord. 3. An option to attach the holder vertically again via carabiner/parachord. It should hold up to 7 spools of tippet. In the attached photos I have on 6. I have included step files for the separate parts. Printing Tips: All items should print just fine without a brim but feel free to add one if you want the extra security. I've slowed down the printing speed to ensure the threads come out cleaner but feel free to speed it up if you'd like.
