Hello Joe!
Thanks a lot for your comment!
I have updated my workbench a little - under the bench itself there is, a little unfortunately, the heater/radiator installed. I had to solve the problem of how to allow the hot air through, but stop little parts from falling down and getting lost forever. I have solved this by installing a piece of plastic tubing with grilles and sealing the edges of the shelf:
I have painted the tube because the white plastic it was made of looked ugly. But then I had one more idea - I hung a picture over it, one that I got from my lady for Chrismas:
Now it all looks prettier, don't you think?
Thanks for looking and have a nice day
