To print an unlabeled RD09 shell, print RD09_Shell_Blank.stl.

To print an RD09 shell with the label on a single-color 3d printer:

• Print RD09_Lable.stl using a skirt distance of at least 6mm.
• Without disturbing the build plate, remove the skirt and change to a contrasting color filament.
• Print RD09_Shell.stl.

The file RD09_Shell.scad is included so you can change the text using the OpenSCAD customizer.

Voxelab purple PLA is a reasonably good color match to Morse Micro purple.
