Best filament for durability as bushings

[airscapes]

Would like it hotter but with the electronics board inside the enclosure the manufacture suggest keeping it under 110F (43.3333C)

Before adding the thermostat it had gone as high as 112F (44.444C) and suffered no issue other than the PLA spool support drooping, but that has been replaced with ABS. And yes there is some shrinkage causing the very tips of the corners to lift a bit.

Adding a 1.5-2mm filet around the edge of the face that is on the bed, along with a brim that is just about attached .04mm offset eliminates most of the lift.

The parts I am making are small and mostly 100% infill, so solid abs, as they are mechanical in nature.

As I have mentioned in another thread, the ABS I am using is really nice stuff, $40US a Kilo vs the cheap Esun but there is never an issue with thinness variation.
