• These STLs are all rendered to print at 0.2mm layer height, including the first layer so 0.2 mm layer height is best.
• I print with PLA. I've had some success with PLA/PHA but plain old PLA works better.
• First layer calibration is important--if you print too close to the bed the bottom layer will be solid.
• Supports are not needed.
• I recommend doing a test print tiny one first.
• Don't over-extrude.
• Do NOT over-extrude.
