Kyosho Blizzard Sprocket Mod For Metal Tracks

The sprocket mod is great, if you've got plastic tracks...
The metal tracks don't have the center bands so they fall into the gaps and get stuck.
This mod of the mod adds a thin disk at the center to prevent that.

Print in PETG or Nylon for best results.

Print with supports i guess, unless your printer bridges really well.

I included the OpenSCAD file for additional modding and also the fixed sprocket-mod.stl as the original has holes in it which prevents OpenSCAD from rendering it.
