Human Factors
It happened when we were doing 45 degree maneuver to enter the left downwind at OBE.  We did radio call twice when we were maneuvering.  While we were almost at downwind; there was another aircraft using his high speed to bypass my left side. I had to do the 360 degree to avoid it.
Small aircraft pilot reported an NMAC occurred while entering the OBE airport traffic pattern when another aircraft flew by them at high speed.
