I think they would be more practical if I printed them larger, but the fact that Open GB can print at this size and produce something that meshes is totally amazing!!!
Question, thoughts on what causes that little bit of bubbling on the surface?

Matthew Fiedler The zits on the surface are from one of two causes:
1) File has too many triangles and printing at high speed causes a buffer underflow condition (printer runs through the gcode too quickly and pauses to refill the smallish move buffer). Fix one of two ways 1) deciminate the triangles using meshmixer or 2) slow down print speed
2) Bumps caused by start and stop points of each layer. Fix by adjusting the retraction and extra restart values.
If the bumps are not lined up as per the simplify3D settings then most likely caused by Point 1) above.

Shawn Fitzpatrick Thank you, let me try those.

Shawn Fitzpatrick Well in hind site, I rather messed up that experiment given that I didn't reprint the same file at lower speed. On the other hand, dang, that is some pretty sweet, VERY smooth surfaced printing!!! Cheap CDN$10.00/pound PLA filament too.
This is printed at Standard resolution, using the default Open GB profile for Simplify3D, with the exception of setting the bed temp to 0 and print speed to 3000 mm/min
