Geared Spring Alignment Hammer - for filament spool auto rewinders

This is a very simple (and almost undoubtedly overbuilt) tool for aligning the geared springs included in many filament auto-rewind systems.

The measurements and sizing for the tool were explicitly based on this model but are likely to work for most related designs:

I was having trouble aligning and inserting the geared springs for my auto rewinder, so I made this simple tool to help insert them level (holding the case, so I was inserting from the bottom) and applying some even pressure.

MAKERS: Please post a picture with comments here of any prints/makes you do from this model so that I can see how people are using it and whether you are finding success with it. Thanks!

and likely many other similar designs.
