Thread Spool and Bobbin Holder

I created this after being tired of searching for the same thread spool color and bobbin thread color :D It is 82mm tall (3 1/4 in)

Holds spools with a diameter up to 1 1/4 in or 33mm and has a hole in the center of 1/4 in (or 7 mm) or larger.

I printed this with a brim, it seems to keep the bottom flat a little better than without the brim.

.2mm print setting

Someone else on here has a design for the bobbin holder (shown yellow in the pic); I'll see if I can find it and add a link.
