Like camping in the middle of a field?  Like cold beer? This mod is for you! Easily drag your cold box through a field with this off road wheels.  They fold down to give ground clearance, and fold up to sit flat.

Uses:

• 1 x Igloo Ice Cube 60 (may work with others?)
• 2 x 8mm threaded rods (from an old mendel…)
• Some M8 washers, nuts and bolts 
• 2 x 3D printed arms
• 2 x scooter wheels (I used: https://www.amazon.co.uk/gp/product/B071P7DYC3)
