Winter Solstice Bobbin Discs for EEW Nano

I had someone respond with concerns about balance. Because of that, there's a v2 with more rings on the "thin" side and no rings on the "thick" side of the tree branches. Choose what you like.

I'm not too worried about the balance of the first iteration because of the added rings, and because I took a coaster and tried it, unaltered but for a drilled hole, as a drop spindle whorl and it spins just fine. Also, the nano is a low-speed travel e-spinner with very small bobbins, so the balance isn't as big a concern as it would be on a larger, faster spinner.

These are only the bobbin ends. You need to print 1x eew_mini2_bobbin_tube from https://www.thingiverse.com/thing:3262290 and either 2x of the "gf" (requires glue) or "pf" press fit disks per bobbin.

NOTE: The "flat" end is an experimental disk that makes a bit more space on the bobbin at the orifice end. It comes out the same overall length as the usual bobbin To use it, print one flat and one of either version of the disk w
