this simple extruded design made in fusion 360 and inspired by the SG-1 Coaster by Trevor Day (EnterpriseXDDesign on My Mini Factory)
I design this four colour offset coaster using various heights to make colour changing an option.
when using it as a coaster the glass only sits on the four bronze chevon pieces and the outer border(s)
there are multiple ways of changing colours mid print,
1: Prusa Control.
for me the easiest way was to use the option in Prusa control the only downside to this is having no control over settings and getting lots of stringing in the final result but not everyone has a Prusa and this will not work for my ender 3

2: using cura
once you have sliced the model you can go to layer view and find the layer number to do the filament changes remember these then go to Extensions>Post Processing>Modify G-Code
once clicking the modify g-code button you can input the different layers for the multiple colours

3: changing the colour manually
the most time-consuming way but the one with the least amount of prep work with this method you will have to watch the whole print( which isn't all that different than what I usually do :} ) and keep an eye on the z height the whole time changing the filament with your printer controls which are usually in the tune section under print temp

Note: slicing at different layer heights in Prusa control will not give you the same height as my measurements
use these as a guideline and do your own measurements before printing
eg 0.2 gives me 1.80mm as the
measurement where 0.05 gives 1.55mm
when using Prusa control or manually changing the heights to change the filament are
these where the measured measurement I took from Prusa control
base layer (black) 0mm
bottom chevon (silver) 1.55mm
"SG1" (white) 3.25mm
border and other chevrons (bronze)3.70mm
