Wheels for a Cardboard Box

thingiverse

I designed these wheels to make it a bit easier to lug around a large cardboard box. Might be helpful at the airport for example. I just taped them on for temporary use, but you could also use hot-glue for example (or even screws if the box is made of stronger materials such as wood).For the axles, needs #8-32 (or 4mm) screws, optionally #8 washers, and optionally 6mm x 6mm x 5mm ID nylon spacers for a bushing. (Two STL files are attached; one that uses the nylon spacers for lower friction and one that doesn't require them.)
