Best filament for durability as bushings

[airscapes]

Well if you are so inclined I have attache 2 models that can be used to verify the your are correct. I typically have first layer height set to 100% in S3D as I don't need to compensate for anything being the Z is set per my layer height. With at 3.5 nozzle and extrusion width of .4 the 2 models I will attempt to attach are for .2 and .3 mm layer height and should be 2mm and 3mm tall as per the names. I adjust M206 Zxx.xx to produce a model that this .02mm shorter which seems to provide the best sticking power without first layer distortion. You can place these in a grid to check level as well. Just measure the height of the completed model with a digital caliper, you would be surprised how accurate your M2 is. These are only 16mm square if I recall so does not take long to do.
