I'd happily make lots of them, but I've not got time now with being at University.
I will probably make some in the holidays. The issue is which motor to choose as it's always a compromise between collet size and max rpm. The ideal way to do it is get a motor which will take an ER20 chuck and rewind it to get the required, higher, rpm (well, kv strictly).
