This is a keychain flashlight made for the Colorfabb Timelapse Contest 2015. It should show a way to create overmolded devices only with your FDM-printer. Watch the video to see how it was made. Here it is a simple keychain flashlight, but you can overmold whatever you want, e.g. microcontroller. If you achieve a completely closed case you can protect your system very easy against water and dust. If you like it, please vote! Thanks a lot!
