I am in the middle of constructing my Mendel90 and some of my first prints will be spare parts for the printer.

What parts are prone to break? (ie what should I print first?) And what fill, layer height etc. should be used on the printed parts?

Extruder gears wear out but if you keep them greased they last a long time. The Wade's block and its idler tend to develop stress fractures over a long time in my boxed machines, where the temperature is high.

The print settings I use are in the Reprap wiki Mendel90 page I think.

I have just finished building my kit from Chris, So far very pleased with the prints i have done.
i am getting some stringy layers on a walled hollow 25mm box but i think I’m printing the PLA to hot.

Seeing this post reminded me i should print some spares before i actually need them smiling smiley

Lithium Grease, as per page 67 of the design manual. You can buy it from most hobby shops or ebay.
