Locking tab for Super Grandma's Favorite Filament Clip

This is a locking tab that is designed to be used with the Super Grandma's Favorite Filament Clip by SkeletalPrints.  The original clip is great and I very much like that it moves freely along the filament allowing it to be left on while the filament is in use. However this is also the source of my only issue. in some cases it has allowed the filament coils to work loose as they are handled. This model is a simple cam style lock that can be threaded into the open center space on the captive side of the ‘Super Grandma's Favorite Filament Clip' .  when standing perpendicular to the clip base, it should allow the clip to move freely along the filament, but when pressed down parallel to the clip it should cause the filament to bind, preventing it from sliding while being stored and handled. 

Update - The v5 design addresses a potential binding issue when the clip was supposed to be unlocked. The actual model will now look slightly different that the ones in the pictures.
