I couldn't find a replacement part that was both sturdy and reliable, so I decided to make my own. To make it as tough as possible, a 3D-printed pin needs to be inserted to help it withstand weight and pulling.

I also designed it as a two-part system because, in certain situations (such as tight spaces), the screws might not be accessible. With this setup, you can first mount the bracket and then connect the spur gear part afterwards using the pin.

In my particular case, PLA is strong enough, but I recommend using ASA or PETG if the part will be exposed to sunlight.

If the spur gear part is too long, it can easily be shortened from the top with scissors or a knife
