I have to get almost 11 sprockets to my BIGCNC. Two of them will be big (48 and 36 tooth). I decide to try to cut them myself. I found a script on Thingiverse (link) and create with it one HTD 3M and HTD 5M sprockets. With Cambam I convert STL to DXF and prepare files to cut. Each sprocket is made from two identical parts and put together with 4 screws.
This is what I receive. Assembled HTD 3M 20 tooth:
In progress HTD 5M 36 tooth:
I know that sprockets are not expensive now days, but it is so much fun to cut them myself.
