Trini's Tiny Tunnel

You create two 1f diameter portals on two flat surfaces you can see within range. These portals are treated as being 1 inch apart, and it is possible to see, listen, reach, cast spells, throw objects, and more through the portals.

The spell ends if either surface moves independent of the other, and if an item or bodypart is through the portal when it closes, it is forcefully ejected with 1d4 per feet of the object ejected. The object may snap if enough damage is applied this way.

For each spell level beyond 2nd, you may either extend the range by 30f or the diameter of the portals by 1f.
