Support for 3mm-1/8inch plexi cover

This is a simple piece I use to support 3mm plexi covers for my printer.
Larger picture shows the idea. The supports shown there are an older version.
To be mounted on the lower 2020-profiles. No special printing requirements.

Plexi is ok to keep the printing area hot enough for ABS and other warp-sensitive stuff. It has also (at least for me) the huge advantage that you can keep an eye on the internals from all sides ;)
