This is an airsoft WE 1911 magazine follower modelled correctly with the slide catch off center as it should be. Had to make this one because the other ones I found on this and other sites are incorrectly modelled with the magazine catch centered on the piece. Instructions Im printing with PLA 25% infill with the piece resting on the magazine catch. Since it is a very small piece I find that having raft is a must. Need to do cleanup afterwards but it works! :)
