This is a mount I made to attach my Proxxon IBS/E to the Shapeoko 2. It places the spindle down and away from the Z-axis carriage to maximize the Z travel. Z max is now possible without colliding with the motor mount, and Z min places the chuck 45mm from the wasteboard. The shape conforms to the original aluminum mount piece to use it as reinforcement, and also latches onto the Z carriage plate itself. I printed a completely solid piece and it's definitely sturdy enough for cutting soft materials. If I make a top mount I'll certainly post it here. Enjoy! See Instructions tab for mounting hardware.You'll need 2 M5 25mm socket head screws to mount this through the center holes of the original aluminum mount. I picked up a few from Home Depot: http://www.homedepot.com/p/Crown-Bolt-M5-32-x-25-mm-Internal-Hex-Socket-Cap-Head-Cap-Screws-3-Pack-37178/202836108 To tighten the spindle to the mount just reuse the long M5 bolts that's intended for the outer holes of the aluminum amount. You'll need an extra M5 nut on the other end.
