Astrodymium's # M54-SPACER-RING spacer rings slip over the M54 male thread of an adapter/extension tube and are primarily used for fine tuning backfocus for astrophotography, but they can be used for other purposes as well.

The width of the rings is 3.95 mm, and the inner diameter is 0.5mm larger than the specified size, for good clearance on the threads (They will not get stuck and are easy to insert or remove).
