Here are some more prints with the CubeX.
Note: All prints are with PLA.
I am quite impressed how accurate and consistent the parts are printing.
Hole locations were right on. I do not have the means of measuring them exactly, but the mating parts fit to the screw holes.
PLA taps and drills quite nicely (slow speed to not melt the plastic) and the threads are quite strong for plastic.
Since PLA is not as flexible as ABS, snap fits don't work as well with PLA. (I have only tried one snap fit).
In some cases you want to adjust your design to get the proper fit and not be too tight, but it is predicable.
For example the clamp around a cylinder. Knowing that the inner diameter of the clamp prints slightly smaller, I increased the diameter of 2.530" on the model by 0.01" to get the proper clearance to fit on the cylinder.
Also, some parts that are designed as machined parts, might need to be modified in some areas, due to less strength and higher flex of the plastic part.
