Bruder D5 Bulldozer two piece drive sprocket

This is a replacement for the factory drive sprocket on a Bruder D5 Bulldozer to be used in an RC conversion.

This part accepts M3 socket head bolts to bolt the halves together - a nut shouldn't be required, but the spacer design will accommodate one.

Notes:
The picture shows a small center cog that is no longer used - it was intended to align the parts and take the drive load if they were to be glued. Removed for easier printing.

I'd recommend at least 1.5mm of total wall thickness
