HO scale ballast spreader. Clean slate model inspired by other designs on Thingiverse and the mass produced Proses design.

This has additional clearance for use with Code 100 rail, pictured on Atlas flex track.
Unlike other designs, I added tapers to the rail clearance area to allow it to follow tighter curves, and to be able to rotate slightly as it goes to vary the width of the shoulder.

Tested with Woodland Scenic fine ballast, should work with others but may need the slot dimensions adjusted.
