This is Corvo's Folding Blade (ArnmmA inspired design) without the help of @arcane_design / OKlamity37's files (Thank you so much for sharing!) which could not be possible. This comprised of an inversion of the design and a remix of ArnmmA's, mainly lengthening the blade and eliminating wobble, also to many aesthetical adjustments to count. At extended it is 70cm long total, 34cm blade, 27.6cm (plus 8cm added) hilt. It is very similarly assembled to ArnmmA's design. I've printed it on a bamba pretty to successful results. If your printer isn't finely tuned you may have trouble with parts sliding as freely. Best to use PETG but I used PLA on everything but the hilt tiret which *needs* to be something stronger than PLA. Be Warned.

Hardware needed:

Small rubber band for tiret lock
Short 3M screw for latching hinge
-e wire dia. 2mm and -m wire dia. 1mm

Maybe some silicone lube

Won't be answering any questions as I've moved on and it's a very old project too full of mistakes and poor workflow I had no knowledge when starting this so a lot has been done better. In the spirit of shareability, freedom of creativity and innovation, I'd love to just get it off my hard drive and onto other creators to tinker and have fun with. Enjoy!
