A foraging wheel that can be lifted off the side of that cage for easy refilling. Simply remove the clamps on the sides and lift the main wheel off. Now you can replenish your rats' food/treat supply without having to awkwardly reach into the cage at the same time.

Notes: -All parts are designed to be printed at a layer height of 0.2mm in PLA. -To make the wheel spin more easily, slightly loosen the center screw after tightening it down all the way. -Tolerances on the ‘clamps’ are meant to be tight. -Make sure the center M4 screw doesn't stick out of the back or it will get caught on the cage. -Also see my “simple” foraging wheel design: https://www.printables.com/model/865998-simple-rat-foraging-wheel

Non-Printed Parts: -3x M4 Screws (2x 30mm+, 1x ~40mm) -3x M4 Nuts
