Summary

A wheel for Ikea's 'Kompliment' large plastic store box.
It clips into the existing slots on the box.

Instructions

Print 4 off, detatch wheel and discard its support ring. Slide wheel into lower bearing hole, click into top.

I used ABS at 20% infill, 0.2mm sliced in Cura (Skeinforge) using dwindle and retraction on Ultimaker. No support needed.

The wheel/shaft is printed offset to minimise string bridging - it can be printed in its bearing holes, but takes a bit of fiddling to get spinning due to print artifacts.
