The goal of this construction is that you can pick 2 guitar strings at the same
time without timeshift. Or you use the other side of the guitar pick to pick one string.

The thickness of the guitar pick amount to 1 mm.
When you use cura you can change the thickness in the following way:
1.) load the guitar pick into cura
2.) mark the guitar pick
3.) choose scale (menu on the left side)
4.) set uniform scaling off
5.) change the z value from 1.0 to 0.8 or 1.2 etc

When you want additional a text on the guitar pick then make following additional:
6.) load one of the available text
7.) open Preferences --> Configure Cura.. (menu on the top)
8.) switch of Automaticaly drop models to the build plate
and
Ensure models are kept apart
9.) mark the text
10.) choose move (menu on the left side) and change the z value to the thickness from the guitar pick. For example 0.8 or 1.2 etc
11.) move the text over the guitar pick

When you want to print the text in another colour, you can stop the print at height ....
(thickness from the guitar pick), change the filament and resume the print.
But this is only possible when you print at the same time guitar picks with the same thickness.

When you want to print guitar picks with the same colour for guitar pick and text it is possible to print guitar picks with different thickness.

Have a lot of fun with the guitar pick construction set.
