Made a series of TPU plugs for electrical conduit getting embedded in concrete foundations.

Made a bunch of 3/4in and 1in plugs last week but just made a 2in pictured. It is a thing that does not exist, which seems silly obvious. This goes in the concrete just below the surface so they can polish it before these plugs are broken out with a hammer and wire gets ran.
If the top bevel was opposite you could pull it out after concrete was poured/polished since it would have draft, instead of trapped by the angle
Might get knocked out or loose.
True , good point.
