I created a tool for unclog tool for unclogging the hotend and extruder.
The problem I had with the Makerworld models is that the needle is always too short to reach the hotend.
Thats why i designed my own tool.
I found the parts on aliexpress:

choose the “without printed parts”
The model can be printed without support.
Just use a brimm for better adheison, as the part is quite high.
