In case you are using langtechnik quickpoint QP52 clamping systems - this part replaces 2 of the individual blue protective plugs. It allows a rather quick placement and removal of 2 plugs at once.
Check the quadPlug to replace 4 plugs at once.
I did not apply any special slicer settings and the part just fits perfectly.
NOTE: The dualPlug is not flush like the blue individual plugs - that might be an issue when using a large vise on a multi plate.
6 solids shells are recommended to get a rather solid part that can be held down by the QP52 system.
