Protects your tape from dust and being damaged.
This caps fits perfect to Blue Tapes. For other tapes you might simply adjust the parameters in Customizer.
Why not branding it with your name, school, shop, homepage or something else.
A separate text file for dual extrusion is also available but not necessary if you use single extrusion.
If you are looking for a sample code for Customizer or OpenSCAD, it may be worth looking at the SCAD file. It is fully customizable but also pretty simple!
Layer height 0.2mm or 0.3mm works perfect. 0.1mm should work also of cause.
multicolor single extrusion:
change the color after 0.6mm printed.
I am using natural beige up to 0.6mm
remaining layers black or other color.
I have added a separate text file for dual extrusion. But I haven't test it, I have only a single extrusion printer.
