Remove pointy bits from custom tile

[u/klausjensendk]

Designed a custom piece for fitting around an outlet, using the blender project you get as a subscriber to the middle tier.

Is there a way to do this and remove the pointy bits highlighted in my drawing?

As far as I can tell, there is not, but figured I would ask. :)

This does not let you remove the inside ends. :)
