If you're looking for something fast and easy -- take a chunk of styrofoam, make what holes you need, and cover it with foil wrapping paper.
You probably won't find any perfectly cubic blocks of styrofoam lying around, but virtually every large piece used to package computers, tvs, etc. has an area with a pleasing and functional shape. While wearing your best over mitt, heat an old butter knife on a stove burner and use it to make nice, clean cuts (you'll do a lot of trial and error to find the right temperature and speed -- it's a knack you have to pick up on your own).
Make holes by heating nails held in Vise-Grips. If you need large diameter holes, try making three overlapping holes at the points of a triangle. Line holes with wrapping paper.
Wrap block with foil wrapping paper, using double-sided tape to hold it down around holes.
I made a temporary block like this because I had to keep some small tools handy but my desk need to be neat and presentable because of VIPs touring that week. It was so handy I used it for years.
