HyperCube Belt Tensioner

This is an addition to the Hypercube design from @Tech2C.
It add to the existing belt clamp und allows to tension each belt separately.

The block height is 10mm. The additional space requires the M3x10 clamping screws to be replaced with M3x20.

For the belt tensioning you'll need 2 more M3x20 screws and 4 hex nuts. 2 for tackling the screws in the block and 2 for countering against loosening. The smaller notch needs to be facing the x-carriage to allow movement of the belt while tensioning. Make sure the screws turn nicely in the caps without gripping of the thread in there.

**Printing:**
Print the caps upright (like a half standing soda can) to be more stress resistant while tightening the belts.
A little sanding and deburring may be needed to move everything smoothly.

**Parts needed:**
1x Tension Block
2x Tension Caps
5x M3x20 screws
3x M3 Hex Nuts

**Mounting:**
Add the block on the x-carriage and the original clamp on top of the block.
