Designed this for Parkside (LIDL) angle grinder base. The one on the original seems to have a design flaw, the head of the tool hits on it and doesnt let it cut all the way down.

I also designed a 45 degree addon because this is the usual change I have to make. Instead of readjusting everytime, clip this on and it's ready to cut.

Printing:

As this piece doesnt take any other load that the one from the built in vice, anything more than 20% is not needed. It would be better to go for 5 walls perimeter. Support is only needed for 45 degree addon, on the edge that overhangs.
