SummaryGot tired feet? You'll love this! After trying to roll around a foot massager on the floor, I felt compelled to design my own that doesn't walk around on the carpet. Enjoy!InstructionsThis is an 8 roll device. It can be expanded on but you'll need to create a bigger housing. The rollers were printed in halves and glued together with the help of a 1/4" bolt. Once the glue is setup the rollers can then be stacked together on an all-thread rod that runs through the housing. 2 flat washers were used on the two inside extreme ends for a tight fit. ..and yes it works well!! enjoy!
