About this 3D model

Hi there, I was cleaning and broke the last hook for cleaning small hard to reach corners and thought it should be possible to print that hooks. Therefore, I made a spatula grip and diffrent heads for it. To connect a head with the grip I used threaded inserts and grub screws in M3 It is possible to print everything without supports but the loop of the loop head has to bee directly on the printbed. I used PETG (grey) and PLA (copper).
