Root 3 CNC 65mm clamp allowing trim router to go 20mm lower than original

This is an alternative spindle clamp for Root 3 CNC that allows Makita/Katsu routers to sit lower on the machine. Mine can now go about 10mm below the bed with a 50mm long end mill.

It also has space for 4 captive nuts on the front for mounting accessories.

Edit: This is now V3. It has beefier construction all-around and slight improvements to bolt head accessibility.
