|Stenomod with 3D printed case|
As I hope you can see I've put an extra rubber foot on the inside edge so they tent just a little bit. That's part of the point of the getting them off the wood deck, being be able to adjust their position more flexibly.
If you'd rather have 3D printed cases like this than the wooden deck I've been offering, let me know in the comments. I'll keep working on it.
