This design is for the Wanhao Duplicator i3 V2.Place on the Z-Axis beam and hang your scraper just like the original design for the V1.
This design has a little bigger opening to better fit the frame and the end hook removed so that the scraper that comes with the V2 will fit.
There are two models,with a bump and without. Print with the part laying flat and not standing up.
I also use another one on the other side to hold two pliers/cutters.
