About this 3D model

Made this anti-fall locking spool holder to hang my filaments above my printers. I have a configurable shelving system under which I keep my stuff. Since shelves are strong enough I figured I'd feed filament to my printers directly from top since they are all direct drive now. This way heavy filament spool won't act like a pendulum on top of my printers. It has two holes from which you could hang or screw one side alone to a wall or something if needed. I'm using reusable cable ties to hang for now since they are pretty solid and I can re-adjust the slack. Printing tips: Print the knob with shaft sideways so it will be stronger. It will require support this way but it will be way stronger. Instagram post for upscaled version: https://www.instagram.com/p/CKg0JINDXwv/
