That's a good idea Nebula, I'll see what I can get together here shortly. Thanks!
As far as the cuts on the surfaces go, on the stepped design, a large radiused cut wouldn't work very well, tho something much smaller would be an idea. Those steps are only 3/4" tall.
The felt colors I have around are the basic colors, but can get almost any color anyone would want.
As far as wood goes, I have Red Oak, and can be stained, or left natural, and I have some walnut. These I use mainly due to ease of working, and they look nice, and the wood doesn't cost an arm and a leg.

I can get many different woods, problem is I have to get so much of it at a time, I can't buy just what I need, and that makes it awfully expensive to do a custom order.
Keep in touch, feel free to ask any questions any time, and when you are ready, we'll figure something out.
oplholik,
I like Mikey3's shape.
Perhaps it could be combined with the side cuts like this one (on all vertical surfaces)?
Do you have an updated wood selection?
Would be great if you could also post a list of devices/mods you already have the dimensions for the holes.
A list, preferably pics, of felt color choices would be great too.
I know we had an email discussion about these a while back but I am getting closer to going forward - just need the above info.
Thanks!
