A tall houising for micro gear motors used in antweight robotics. These motors are simular to these: http://www.hobbytronics.co.uk/mm-gear-motor-50 Unlike the original ones, the grooves which fit over the plates of the gearbox are not here in this design. The idea is to lock in the motor by heating the plastic and pressing it to firm around the motor. I am using these on mine and they work fab :-)3 file types are included. The standard type which is available for purchase is named 'motor housing'. These are designed by myself and fit well. Other 2 allow a tall stand-off from a bottom plate. These fit the standard Pololu wheels suc as these: http://www.hobbytronics.co.uk/wheel-32-7 This second design has ears for those who have issues printing small parts.Once printed, insert motor and gently heat plastic around motor, then squish slightly to 'lock' motor into place :-)
