Thanks! I've been wracking my brain trying to remember who made it!
I painted it with the green and tan rustoleum 'Stone' paints.
Using your pointers I found that the official name is "Little Wild Thing".
The only problem I ever had was trying to squeeze all the motors in, it was a tight fit. Most of the time I peel a little paper off the outside of the 13mm motors to get an easy fit.
Not sure if there are instructions/plans online, I could always take measurements of mine if people really want it.
