Three triangular wedge filler pieces (30,45 and 60 degrees)

This addon aims to allow you to be a little more tidy and creative with the way you place your plots.
It adds the following:
-30 degrees wedge:It allows you to create a closed circle of 12 plots.
-45 degrees wedge:It allows you to create a closed circle of 8 plots.
-60 degrees wedge:It allows you to create a closed circle of 6 plots.
-A support pillar you can snap under the wedges for aesthetic reasons.

All wedges have various snap points on the snapping sides so they can point both to the front or the back of the plot.
The 60 degrees wedge can be snapped to the back side of plots too, not only the sides. The wedges can be found in the wooden floors and foundations category of the workshop menu.

The wedges have vanilla snap points too now, so you can snap stairs,floors,railings etc... to the sides of a wedge.
