Cold pull push

"Cold pull push" is a small two piece jig that helps to pull out an allen key that has become stuck inside the hotend when doing a cold pull. To use it you first need to assemble it by winding the rectangular nut onto the main part. It should be a tight fit but wind it all the way down ending with the slit in the main part and the slit in the rectangular nut in line with each other. Use: As you insert the heated allen key make sure the short end faces forward (in line with the slits). Once the nozzle has cooled, slowly unwind the rectangular nut. This will slowly push (force) the allen key out. It does work in PLA but PETG is preferred for both parts and will give a better action.
