Filament Sample Reel

**V2 Update**

I've added a set of V2 parts. The V2 parts should be backward-compatible with all V1 parts, however, there are improvements:

* The Screw end has 1 mm shorter threads to ensure that the parts screw together with no gap on the inside
* The Screw end now has keeper holes for both 1.75 mm and 3 mm filament
* Bases are now available in 60 mm (V1 size), 40 mm, 30 mm, and 20 mm widths

The 40 mm was a bit too wide to save any room in my filament box, and the 20 mm was too narrow to easily load filament, so I added ao 30 mm version that should be, as they say, just right.

I've left the V1 parts up just in case someone wants them, but there should be no reason to print them anymore.

**Yet Another Filament Sample Spool.**

I couldn't find one that fit my needs, so here is my design. It has an inside diameter of 70 mm, so small coils of filament fit easily. It has an outside diameter of 180 mm and a width of 60 mm so it fits normal filament spool holders, a
