Sheldon created a spacer made of stainless steel, which fits v1.0 and v1.1 machines.
Kits are made to order and to the thickness of your choice (default thickness for v1.0 is 6.8mm and v1.1 is 3.4mm).
The spacer will work with the stock shower screen as well as the CI 200 IM screen shipped with the "PRO" model machine. Latest batch of spacers are made from 316 Stainless Steel and all other parts are 304 Stainless Steel.
Each kit includes the following:

The photo below shows the intended layout. When using the CI 200 IM screen, shims should go between the inner spacer and screen - it fits better. Order does not matter with the stock screen.
Shims are used only as necessary or as desired. Without any shims, the screen will sit flat. Adding shims will bring back the screen's convex shape.
