Imperfect wheel to fix toy prams

thingiverse

This is a straightforward wheel with a central protrusion that features a conical internal shape designed to snugly fit onto the axle of what you're trying to repair. Words can be reversed (via SLWKS) to say anything: this one reads out (and leaves behind its impression of) I'M FAE DON'T YA KNOW! BOO!! (followed by a mischievous little smiley face). It could serve as a good starting point for someone who needs to fix a toy wheel of some kind. The diameter is 75cm, and it printed well at this scale, taking approximately eight hours in total.
