Dillon xl650 casefeed arm bushing for .357

thingiverse

thing is for casefeed arm of a dillon xl650 press. The medium case bushing lower diameter is too big so the cases block and do not fall down. This bushing is smaller in dia, so the cases wont block on the edges. Unfortunately it doesnt slice in repetierhost because .2mm is too big. But perhaps someone can use this.
