Replacement dragging sprocket for DeWalt DW50 Planer-Thicknesser

This is a replacement sprocket for our old but trustworthy planer-thicknesser. The old plastic sprockets that drive the infeed rollers were significantly worn out and after one broke and I couldn't find any replacements I decided to model my own.
This was my first design, so if you're a pro don't hesitate to leave constructive criticism, I'm still learning. ;)

It has held up reasonably so far as long as you're careful not to overload the machine printed sprocket by letting the planer remove
