This is a new version for optimized 3D printing experience. Now you don't need screws nor metal wire as all parts are 3D printable except fishing line/yarn and straps. Building is quite simple and I have added pictures of the building process. No special print settings or specific material needed. I personally made this out of PLA with very default settings and added supports. Short video of the use: https://youtube.com/shorts/80kiRxBVz8w?feature=share
