Bosch integrated microwave door hinge issue
Discussion
The door on our microwave has been more and more difficult to close tight enought for the safety interlock to allow the microwave to run.
I suspected the springs on the door hinges has stretched, so spent £42 on a pair of them. Just taken one side of the microwave to bits to fit them and the old spring are fine. The issue is that a nylon guide wheel for the hinge has developed a flat spot just through wear and tear. Once the wheel has turned to the flat spot, the hinge slides doesn't move any further without a shove. I'm assuming both sides will have the same issue.
This is the part with the nylon wheel on:
These are £26 and £36 each! Not sure why the different prices for LH / RH

Before I spend even more, anyone got any bright ideas how I might fix them? Or a cheaper source for the parts?

Can you get the wheels off? It's not impossible to get a new one turned on a lathe (reshaping the existing would probably make it too small) but 3d printing might be easier.
I'd also try to work out why they wore flat & make sure that can't happen again, maybe needs better lubrication.

No lathe / 3D printer owning friends, and the wheel itself looks lie it is riveted on to the bracket.
The microwave must be 14-15 years old now, so I think it is just worn out. There was a little bit of white lithium grease on it, but not very much.
Going to order the parts. In total I'll have spent about £100, and a new one with a drop down door (albeit 900W instead of 1000W like this one) is £699
