    thats kool but i think it would do better if you cut cooling slots in the pvc and taped a piece of pantyhose over the motor before you put it in the pvc,that way you wont cook the motor by it getting to hot.

    You could also trying drilling extra holes in the end plug to allow air in/out. The odds of plugging them with dust are pretty low considering they will be relatively far away from the drilling point and protected by your hand. If worried about the dust, a little cotton in each hole would filter decently.
