Beads!
thingiverse
These are some basic shapes of beads. I couldn't find any on Thingiverse (currently, could just be the new search not working). If these prove popular I'll add more shapes in. If you like my designs please subscribe to my YouTube channel: https://www.youtube.com/channel/UCgItLzb2PnHYKeNAFSx0jpA/
