I printed the original model above and another variant I found on thingiverse. However, I felt both needed a few modifications to make the best use of the item. There has been a blade groove added to the handle to keep it from shifting if pocketed. There are also double magnet pockets added for closure only on the top and bottom piece, this really insures it wont come open and allows you to keep the links loose enought to open smoothly once the magnet force  is overcome. There is also a finger guard on the bottom which is carried over from another variant, along with the thumb indention on the top. I have also recessed the hex pockets on the top so they will sit flush once installed. I have included a carabiner found here (https://makerworld.com/en/models/495667-carabiner-origami-without-brands#profileId-409854), within the print profile so you don't have to look for a good one. This is just an extra as I carry mine on a pack. The objects are arranged to print in two different groups for two colors. This can be modified within studio easily and if ther is any interested I can include a simple single color variant. 

Needed:

• 4ea - M3 x 16mm screws
• 4ea - M3 Hex Nuts 
• 2ea - M2.5 or M3 x 8-10mm screws and 2ea hex nuts
