We have a *SnüzPod* (a baby bed) and a *Alecto DVM 80* (a baby monitor). The two really don't work well together and this little bracket solves that problem.
All you need is a M5 nut and bolt (30mm or longer), the Alecto DVM 80 already comes with a standard camera mounting bolt (1/4-20 UNC thread).
I usually design things in Sketchup to print stuff on my UM1 or UM2. The designs are always accompanied by their source files for editing and a collada file for printing but if you want a particular format, just ask.
