This is a accessory for the Creality CFS latches that open the top. For anyone needing extra grip or adding customization to your build this would be a great addition. Print with normal supports. If printing from STL please mirror it in your slicer to have the same matching model on both sides of the CFS. There are two version provided. One has the arrow embossed on the top which requires less filament changes and the other is flush with the top. Project files are provided as well.
