Circuit Board Coaster

Ultimate Geek Drink Coaster Single Extruder and filament change to be done at Layer 22. This is best done using Cura 'Filament change' option in 'Post Processing' as per screenshot. That only works when your firmware has 'Advanced Pause Options' enabled. It is worth messing with your firmware to get 'Filament Change' option in cura working. Important to know before printing: Two color printing with Cura 'FIlament Change' highly recommended (Layer 22 if using 0.2 layers) Second small image recommended (See '2colorwipedot.stl') On color change you want it to first print to this 2nd image (Round circle) as color changes sometimes put down a blob where they land. See screenshot showing the cura tip showing where it will land in preview mode.

I mainly did the larger holder above to hold my 4 coasters with cork backing. (Apply sheet, cut around edge - easy) This would look good in the following color combinations Green/Gold Dark Green/Light Green Red/Gold Black/Gold Black/Silver Blue/Silver Maybe some others.
