Introducing the Airwolf Quick Release Latch. This new xtruder part eliminates the need to “chase” those little washers on the extruder every time you are closing the pivoting member. You also do not have to readjust the tension between filament changes. It makes changing filament a snap!
This is standard on all 3D printers since 09/22/2012. If you would like to add this latch to your Airwolf 3D printer, you can download the STL here: [wpdm_file id=1] You will need to change out the pivoting member from your extruder and replace it with this pivoting member, then add the new Quick-Release Latch. You do not need to change out the entire extruder, but disassembly will be necessary. Give yourself about 1/2 hour.
After the extruder is disassembled (and your new parts are printed out), first drill out the base holes in the new Pivoting Member with a 1/8″ drill bit to clear up the opening for easy pivoting. Then assemble the Quick-Release Latch as shown below with M4x50mm bolts and springs (most printers should already incorporate these).
Attach the Pivoting Member to the Extruder Body. Then attach the Quick-Release Latch to the Extruder Body such that the 2 M4x50mm bolts thread into the 2 M4 nuts in the Extruder Body.
