Abacus (Ye Olde Arithmetic Device)
thingiverse
This is an Abacus! These machines are used to visualize numbers and perform mathematical operations. You can get pretty fast at it if you practice, and this can help you learn to calculate solutions faster. You'll need 1 Frame_Abacus and either 60 Bead_Whole_Abacus or 120 Bead_Half_Abacus. I chose to print 120 of the Bead_Half_Abacus, and super glued them together. This looks nicer, since the Bead_Whole_Abacus pieces need supports to print. Just my personal preference:) Here are some great videos to learn how to Abacus from The HEV Project: https://www.youtube.com/playlist?list=PLp_0j14In7k64IRvV0Re1ZR6rCF-VWn9T
