X-carriage belt tensioner clamp

After adjusting the tension on the X-axis belt for the zillionth time (to loose = lash, to tight = motor skip), I designed this little tension clamp.

The clamp consists of 2 parts: one goes onto the carriage with the original 2x40mm bolts. The other part gets clamped on the belt with 2x20mm M4 bolts and 2 nuts. The 2 parts are joined with an 55mm M4 bolt and M4 nylok.

After putting everything together, its a matter of tensioning a single bolt to modify the tension on the belt.
