Hornychz: What have you used to make such neat cylindrical holes in your shield plates, and spacers to separate them. Where did you get the little case? I love the method and is what I will likely use. I have homemade my temp/humidity shield using flower pot saucers and PVC drain pipe through the center, where the sensor is installed with fan on the bottom.  It does the job very well, though probably not very attractive. I plan to rebuild using a stiffer saucer plastic.

Hi qldbureau,

Werk_AG helped me to recover my message, so I am trying to post it again:

Making holes is really fast and simple:
1) I use plastic bowls under pots that have a rolled ring exactly where I need to cut like this one:


(one piece 26 cm about USD 0.75)
2) From the outside of the bowl I cut a hole with a manual vertical milling cutter - the circle is doing well because the cutter can "lean" on the outer edge.
3) The hole is horribly "hairy," the material melts during cutting. That's why I'm going to do it manually with a NOGA scraper (with reburring blades BK3010).
4) In all of the dishes at once, I drill the holes with a small drill for centering, then drill the holes with the threaded rod.
5) Today I'm already "lazy" to make spacing posts, so I buy them finished and again according to the average thread rods I used (www.tme.eu).

Very simple, is not it? (Before I wrote it, I'd make the whole radiation shield.) 

Now I have bought another two DIN rail box:
PLC Plastic Shell Box



I hope I did not spoil your opinion about my qualities with the ease of production ...
