Filament Spool Adapter 2

This is an improved version of my [previous filament spool adapter] (https://www.thingiverse.com/thing:4108171). it can fit any spool width, as long as the thread from Part1 passes through Part2 and the nut can be screwed on.

Like the other adapter, it can be used with 2 8x22x7mm bearings and it can be supported with a 8mm rod.

I designed it with DesignSpark Mechanical, the .rsdoc file is included.

Update:

• The thread on Part1 is now a bit longer to fit wider filament spools
• Added an extra 0.2mm spacing between Part1 and Part2 so they're not as tight.
• Increased the hole size for the bearings because they were also a bit too tight.
• Added spacers to be able to fit the 8mm rod with the original Ender-3 spool holder arm
