Two color print (AMS use):
16 filament changes
You can use whichever colors you would like; this is my personal preference. Designed this to use two round mini magnets on the back (I thought I had it for 10mm x 3mm, but measured at 7.5mm after printed). You may have to do a heat press on the magnets
Roughly 2-hour print
Had to mess with a few settings when using the gold silk, but after trial and error it printed like a beast. You can print the files separately with the STLs but use caution as it will have loose items unlike the combined AMS design.
Great gift idea for prior service or those still serving.
