Here's a quick and dirty docking station for the Steam controller.

Tolerances aren't great. It could be a little tighter around the puck itself but it holds it well enough. The mounting rail is too tight but a bit of sanding never hurt no one.

No special printing technique required.

Screw the rail to your desk.
Slide the mount for the puck onto the rail.
Slide the puck into it's mount.
Plug in USB.
Profit!
