Poseable Robot Arm Keyring
thingiverse
A keyring modeled off a robotic arm with several joints can move. I will try to update this thing for re-mixable writing on the square section. Instructions -I have achieved successful prints with 0.3mm layer heights. -There are several very small bridges in the model around the joints. -The only finishing required is to remove the ready-made support material from around the middle of the joints. -Care should be taken not to torque the keychain too much around the joints when removing it from the build platform :) I may increase the joint rigidity to help prevent breaking :)
