Our wheels for the SmartStore Bedroller kept on breaking, so I made a new one.

The wheel prints in 3 parts without support. I made them to fit snuggly together with a snap fit to eliminate the need for glue.

On the first picture you can see how the part originally looked vs the one I made. I made it as similar as possible but optimized it for 3D printing.

You print 2x the wheel and one hex part for every wheel you want to print.

I printed in PLA with 0.6 nozzle, 0.3 layer height, 25% infill.
