Anet E12; quick lock for the SIQUK MK8 Extruder upgrade

After installing the SIQUK MK8 Extruder upgrade, I found one extruder cam like a release that I tried but didn't work out well after the upgrade. I designed this one to slide on tightly over the arm and lock open until released.

If you are using a metal extruder upgrade this might work out for yours.

If you like this design, then you might like these for the Anet E12.
