Hi, this is an excellent little fidget. It rolls freely, and the sky is the limit with color combos. I hope you all enjoy it! Print two of each file and then glue them together for more strength. Recommend four walls with on bases for extra strength and a small amount of lubricant on the bases to keep them from squeaking.

They feel really flimsy at first, but as soon as you glue them together, they become pretty solid.
