I'm trying to create this effect, where a 1x1 half-circle tile seems to 'stick out of' a 2x2 brick at 90 degrees:

This is easily achieved with a 1x1 tile with light attachment, as seen here:

However, that particular piece is quite expensive in my chosen color (either orange or dark orange).

I've tried using a technic axle-and-pin connector, but it looks very bulky and the pin itself is also not available in (dark) orange:

I've also tried various brackets in different configurations, but since they're all square, the edges stick out from under the half-circle tile.

Are there other ways to achieve the same, or a similar looking effect?
