Summary

Learn to count money by stacking US Coins and adding their values.

Instructions

Print the plate and 2 sides and assemble, or just print CoinCounterMathChallenge.stl. It is designed at actual metric size, so you may need to scale it up a couple percent depending on printer settings if clearances are too tight.

I put this model together very quickly... have not printed it yet. I am wondering if the 4 mm gaps between the coins are OK... if anyone prints this out and tries it let me know. I am willing to share .ipt files or fix any issues and resubmit if needed. Thanks!
