Heatbed alignment system - Easy handling

This alignment system is for the use with a 200 x 200 mm² heatbed. It faciliates the operator to manipulate the height of the heatbed from the bottom side of the heatbed. An Allen key access hole is on the bottom side of the plate-clamps.
The design is made for use of m4 DIN912 screws for height alignment and the frame rods and M3 DIN912 screws for holding the heatbed as well as the clamp fixation on the ground plate.
Do not forget to get some springs fitting in the endholders for the heatbe
