Thanks for the hacksaw tip. I have not sharpened a blade yet but I will. Could you use or have you tried drilling holes and pinning the blade for additional stability may be a threaded stub and a washer and a wing nut on top to clap down blade.
I have a 3D printer but I suck at making anything but the practice models. I have not figured it out yet. Where did you get your file for your clicker?
