Other Multiboard plier holders did not work well for holding Vice Grips. Found a metal holder for Vice Grips and made a similar holder for use on Multiboard.

Since the release of this posting, have worked with the model and have made some additional holders with different options. The original holder used a big thread to attached to Multiboard. The new designs use octagonal plugs that fits into snaps or a big thread bolt printed separately. The new holders are also designed to be stronger. Finally, there are three version small, medium and large holders to better fit different sized vice grips. Look for those models: Multiboard ViceGrip Holder plug.

Recommend printing at a 60 degree angle. Also with perimeters set to at least 5. Have printed using PLA or PETG.
