I haven't been very active lately in the forums, but just wanted to share what I found on Thingiverse for our push pins/clips. I'm guessing that some other folks here have also broken some of their push pins/clips under the hood when changing out their battery, etc.
If you have access to a 3D printer, you can print out some replacement clips (recommend using PETG or ABS) using this design on Thingiverse:
