I am a big Tesla fan and therefore I designed a simple keychain on Fusion360. My printer only has 1 nozzle, but if you set a timer, knowing the right time after first print, you can simply pause the print, switch filament and then you´ll have a nice red n white keychain like I do.
You can play with the size in Cura or whatever program you use by tweaking the scale ;)
If you like my designs please follow my instagram @chillinglu (https://www.instagram.com/chillinglu) and subscribe to my youtube (https://www.youtube.com/user/THEchillingLU).
p.s.: I know I didnt print at 100% infill, but trust me it will look better with 100% infill ;)
