Filament Lock

1.75 mm Filament Lock This updated filament lock is designed to prevent unspooling and tangles, meeting all my original requirements more effectively than my previous [first design](https://www.thingiverse.com/thing:3627765). ### Essential Features of a Filament Clip: - No clipping to the spool rim - A visible flag that identifies the loose filament end - Prevention of loose filament from getting tucked under another filament loop - The clip should not need removal when using the spool - Compatibility with any spool type - Easy printing, no assembly required - Simple and easy to use My first design worked but I discovered that on some spools, the retainer could slide and allow the filament to loosen on the spool. I highly recommend giving this improved version a try.
