Browsing around Thingiverse, I found some owl-face buttons. My mother wanted some for a project, so I printed these.

They are about 1.3″ in diameter.

I also downloaded and printed some handy clips for the filament spools, for when the spool is not in use. Up to now I’ve been using masking tape to keep the reels from unwinding. Now I have these clips. I printed three for the Octave reels, (since I have three of those) and one Afinia reel clip.
