25XL037 10mm bore timing belt pulley

I created this for use with the Rotary 4th axis for CNC.

There are holes that can be tapped for M3 to tighten the timing gear down onto the 10mm shaft / bolt. I drilled a through hole on my shaft and have a 30mm M3 bolt going all the way through. I used a tapered head bolt so it would sit flush with the flange to avoid it hitting the body when rotating.

I may modify the flanges a bit to print cleaner but for now it works.
