Hypercube Evolution M

## Time to build myself a 3D printer so here it is.

This is my take on the popular Hypercube Evolution by SCOTT_3D.
The 3D model was made in Fusion 360 and a preview of the design can be found here

### Main objectives:
- print volume of 230x230x300mm
- printer size 390x390x600mm

### Custom parts:
- 12mm lead screws and nuts for the Z axis; (used 12mm because I can source them locally)
- 10 pieces of 3030 aluminium profile 350mm each (for the main frame)
- 4 pieces of 3030 aluminium profile 600mm each (for the main frame)
- 2 pieces of 2020 aluminium profile 170mm each (for the bed frame)
- 2 pieces of 2020 aluminium profile 340mm each (for the bed frame)
- 4 pieces 12mm diameter linear shafts, 450mm length (for the Z axis)
- 2 pieces 8mm diameter linear shafts, 400mm length (for the X Axis)
- 2 pieces 10mm diameter linear shafts, 350mm length (for the Y axis)
- 1 piece 260x300mm aluminium plate, 8mm thick; a 250x250mm plate will work just
