Keter Workbench Paint Point - Remix

Remix of projmantn's great idea to make painter's pyramids that slide into the miter tracks on the Keter Folding Workbenches.

Made the following changes:

- Added to the height of the point to match the height of the Home Depot Painter's Pyramids I use a lot. The top of the pyramid now stands 2" (50 mm) above the workbench surface.
- Cleaned up the model a little bit and chamfered most of the edges to make sure they slide very easy in the miter track.
- Added a hole that should accept a 1/2" dowel rod. I don't have a real use for this. I just got done with the model, saw the large open area in the middle of the pyramid and thought I should try to find something useful to put there. It uses a little less filament and maybe someone will have a use for it.
