paint can shaker can be attached to any drill with a standard ¼" bit.

use this to shake paint cans. print in two pieces and glue the two together. make sure not to glue the fins to the base.

i used petg for the strength and flexibilty. also have extra perimaters where the ¼" drill bit is inserted.

if you find the cans are sliding out print the fins taller to hold more of the can.
