Segmentation Software : Cura (Any 3D slicer will work)
3D Modeling/CAD Software : Chimera

Printer Technology/Material : Polylactic Acid (PLA)
Printer Make/Model : Creality Ender 5 Pro
Print Units : mm
Scale At Given Print Units : 200x, surface model - 175x

Pre- and Postprocessing Instructions 

Cartoon/ladder:
The model was re-orientated using the Auto-orientation plugin in Cura. Printed at 0.2 resolution with wall 4 lines and  20% infill. I have used concentric supports and found to be easier to remove. Nothing snapped during the supports removal. This was an easy print.

Cartoon:
The model was re-orientated using the Auto-orientation plugin in Cura. Printed at 0.2 resolution with wall 6 lines and  20% infill. I have used concentric supports, but this time were difficult to remove, especially in between the base-pairs. Nothing snapped during the supports removal though.

Surface: 
The model was re-orientated using the Auto-orientation plugin in Cura. Printed at 0.2 resolution with wall 6 lines and  20% infill. I have used tree supports and were easy to remove. 

Balls and sticks:
The model was re-orientated using the Auto-orientation plugin in Cura. Printed at 0.2 resolution with wall 6 lines and  20% infill. I have used concentric supports, but I had difficulties removing them. The model snapped into several pieces in the process. I managed to glue it back together, but I would not print this again unless I could print the support with a soluble material.
